-- zip sometimes crashes on some versions of NetBSD (0.8, 0.9 and early
-  0.9-current), FreeBSD (<= 1.1) and BSDI (< 1.1) . This is due to a
-  bug in stdio.
-  Upgrading the stdio package in /usr/src/lib/libc/stdio should
-  fix the problem. See *BSD mirrors in src/lib/libc/stdio
-  You must at least replace setvbuf.o in all the libc's with a newer version.

-Note:  Zip 2.4 was never released.  That code was the start of the Zip 3.0
-effort below.  Some changes and fixes also made it to the Zip 2.3x releases.
-
----------------------- January 21st 2004 version 3.0a ----------------------
-Initial work on Zip 3.0 by Ed Gordon and Rainer Nausedat
- 1. Changed some comments to update copyrights (Ed)
- 2. Changed text in command line messages from zip 2.4 to zip 3.0 (Ed)
- 3. Changes to many files for Zip64 wrapped in ifdef ZIP64_SUPPORT (Rainer)
- 4. Attempt to fix buggy Win32 buffered 64-bit calls (Ed)
- 5. Add functions to zipfile.c for Little-Endian memory writes (Rainer)
- 6. Add functions to zipfile.c for writing Zip64 extra fields (Rainer)
- 7. Major changes to putlocal, putcentral, and putend (Rainer)
- 8. Fixing -F and -FF for Zip64 postponed (Ed and Rainer)
- 9. Command line code replaced.  Global table sets options, long options now
-    supported.  Permutes so order of arguments can vary (Ed)
-10. Fix bug where not allowed to use -@ with stdout but was with stdin.
-    Now can read filenames from stdin using -@ and output to stdout and
-    no longer am allowed to use -@ if reading from stdin (Ed)
-11. Replace stat() with zstat(), fstat() with zfstat() and struct
-    stat with z_stat in Zip64 blocks.  Put 64-bit file calls in ifdef
-    LARGE_FILE_SUPPORT blocks.  Can implement Zip64 without > 4 GB
-    file support but for now need large files for Zip64 support (Ed)
-12. Move port-specific code to osdep.h and win32.c (port specific) and
-    tailor.h (generic) and remove temporary os_io.c.  As OF() is
-    not defined until after osdep.h includes in tailor.h function
-    prototypes for zfseeko, zftello, and zstat after that in tailor.h (Ed)
-13. Settings of ZIP64_SUPPORT and LARGE_FILE_SUPPORT automatic based on
-    port and version of compiler.  Defining NO_ZIP64_SUPPORT or
-    NO_LARGE_FILE_SUPPORT overrides this (Ed)
-14. Bugs compiling scanzipf_fix(...) in zipfile.c and the fix functions could
-    use rewrite (Rainer and Ed)
-15. Add prototype for zfopen for mapping to 64-bit fopen on ports using
-    inodes but not implemented (Ed)
-16. More work on extended local headers and encypted archives (Rainer)
-17. Fix DLL files so now compiles (Ed)
-18. File size in dll limited to 32-bit in structure.  A new DLL api is needed
-    to return 64-bit file sizes.  Current api fixed to return max 32-bit if
-    more than that (Ed)
-19. Add local header Zip64 support and local extra field.  Fixed cast
-    to ulg missed previously that forced zstat to return value mod 4 GB in
-    zipup.c which kept local header code from seeing actual file size (Ed)
-20. Add new option --force-zip64 to force use of zip64 fields.  Could
-    be temporary (Ed)
-21. Fix for VB added to api.c that just store the passed strings internally.
-    Should update api to optionally return file sizes as 64-bit in call back
-    and to accept RootDir and other strings in same call that zips (Ed)
-22. Readme updated to describe new features and mention updated mail group
-    web links (Ed)
-23. Minor bugs in output format found and fixed.  Now can add
-    files > 4 GB to archive and unzip using major unzippers (Ed)
-24. If zip used as filter (zip - -) and sizes exceed limits of extended
-    local header (data descriptor) then set max 32-bit values there.  Major
-    unzippers ignore and use central directory values which are correct.  Can
-    create Zip64 data descriptor using --force-zip64 option but seems no need
-    for it (Ed)
-25. A few bugs in how headers are handled prevented zipping large numbers
-    of files.  Fixed (Rainer)
-26. A bit of an attempt to fix -F and -FF.  Seems to work but not that
-    robust.  More work needed (Ed)
-27. After some cast and other fixes zip compiles on Linux Red Hat 9 using Unix
-    generic.  Added automatic detection of fseeko64 and if detected
-    sets LARGE_FILE_SUPPORT and setting that sets ZIP64_SUPPORT.  Works but
-    could not test large files on the small system (Ed)
-28. Tried to fix bug that prevents zipnotes from compiling when ZIP64_SUPPORT
-    is set.  Still broke.  This crashes the Unix Makefile but after
-    zip is compiled (Ed)
----------------------- May 8th 2004 version 3.0b ----------------------
- 1. Update license headers on more files (Ed)
- 2. Change many ZIP64_SUPPORT ifdefs to LARGE_FILE_SUPPORT where appropriate.
-    Now can test ports using three stages, compile with NO_LARGE_FILE_SUPPORT
-    (which disables ZIP64_SUPPORT) to test base code, compile with
-    NO_ZIP64_SUPPORT to test the 64-bit file calls (assuming port sets
-    LARGE_FILE_SUPPORT) but otherwise use the base code, and without either
-    to test Zip64 if enabled on port (Ed)
- 3. Fix zipnotes bug by moving a ZIP64_SUPPORT block in zipfile.c (Ed)
- 4. Add Large File Summit (LFS) code to Unix port to enable 64-bit calls.
-    Update configure to include test for all needed 64-bit file calls before
-    enabling LARGE_FILE_SUPPORT for unix port (Ed)
- 5. Merge encryption code from zcrypt29 (files from unzip) into zip and
-    enable by default (Ed)
- 6. New man pages for zipnote, zipsplit, and zipcloak (Greg, Ed)
- 7. Add encryption notice to crypt.c comments and to version information
-    in zip.c (Greg, Ed)
- 8. Add Russian OEM EBCDIC support when OEM_RUSS defined in ebcdic.h but
-    Dmitri reports that 0x2F not '/' so make recommended change in cutpath
-    call in zipfile.c used by -D option (Dmitri - Nov 10 2003 email)
- 9. ToDo30 file added to list what's left to do in this release (Ed)
-10. Change fopen to zfopen for large file code and map to fopen64 for
-    Unix (Ed)
-11. ftello64 seems broken in zipup.c on Linux (kernel 2.4), returning
-    negatives past the 2 GB barrier, though ftello64 works in a test program.
-    Likely error in defines.  For now skip ftello64 check for Unix with
-    LARGE_FILE_SUPPORT.
-12. A few updates in Readme.  Needs overhaul likely.  Also verified mxserver
-    is gone and replaced with list addresses (Ed)
-13. First iterations at updating WinDLL for Zip64 (Mike)
-14. Decide to drop backward dll compatibility in favor of a cleaner
-    dll interface.  Decide to add string interfaces for VB (Ed, Mike)
-15. Add string interfaces to dll interface to bypass array limitations
-    imposed by VB and add -x and -i to interface (Mike)
-16. Create new VB example using new Zip64 dll interface (Ed)
-17. Add O_LARGEFILE define for zopen in unix/zipup.h to enable reading
-    large files in unix (Ed)
-18. Combine ZpSetOptions and ZpArchive dll calls to allow removing all VB kluges
-    in api.c to work around VB garbage collecting passed strings (Mike)
-19. Change new VBz64 example to use updated interface.  All works without
-    kluges (Ed)
----------------------- August 15th 2004 version 3.0c ----------------------
- 1. Add date formats in -t and -tt date errors (Ed)
- 2. Add -so to display all available options (Ed)
- 3. Many fixes from Dan Nelson to fix some large file support problems and
-    add large file support to a few ports.  Main change is rather than use
-    explicit 64-bit calls like fopen64 now set 64-bit environment and use
-    standard calls.  Also add a define for 64-bit printf format used to
-    print 64-bit stats (Dan, Ed)
- 4. Changes to Unix config based on suggestions from Dan Nelson.  Check
-    if off_t is at least 64 bit (Dan, Ed)
- 5. Add -- to get_option.  Any arguments after -- on command line now
-    read as paths and not options (Ed)
- 6. Add extended help (Ed)
- 7. Change add_filter flag parameter from char to int as some compilers have
-    problems with char arguments (Ed)
- 8. Changed filter() to do R and i separately so i has precedence over R (Ed)
- 9. Split variable t in zip.c into t (off_t) and tf (ulg) (Ed)
-10. Add quotes to zipname in check_zipfile for MSDOS to allow spaces in
-    archive path given to unzip to test ( , Ed)
-11. Move zip.h include before ctype.h include in trees.c and zipup.c as
-    when ctype.h is first and using 64-bit environment at least on unix port
-    found it defines off_t as 4 bytes in those files as off_t is defined as
-    8 bytes in other files and this changes the size of the zlist structure
-    which is not good (Ed)
-12. Add default 64-bit file environment to tailor.h if LARGE_FILE_SUPPORT
-    is set but no port 64-bit file defines are set up earlier in the file.
-    Should allow other ports to set LARGE_FILE_SUPPORT on the compiler
-    command line to test if the standard defines work (Ed)
-13. Adjust binary detection in trees.c by changing 20% binary (4 out of 5
-    ascii) that used >> 2 to 2% (64 out of 65) using >> 6 instead.
-    trees.c  (Ed)
----------------------- November 12th 2004 version 3.0d ----------------------
- 1. Add global variable for EncryptionPassword in VBz64 example and
-    some other password callback cleanup (Ed)
- 2. Add -W option to turn on WILD_STOP_AT_DIR where wildcards will not
-    include directory boundaries in matches (Ed)
- 3. Add -nw option "no wild" to completely disable wildcards in MATCH
-    function.  Allows a list of files to be read in without worrying about
-    wildcards or escapes (Ed)
- 4. Add -s option split-size but not implemented (Ed)
- 5. Add -sp option split-pause but not implemented (Ed)
- 6. Add changes for WiZ including moving Win32 64-bit wrappers into
-    win32i64.c to avoid naming conflict between libraries in WiZ (Mike, Ed)
- 7. Some large file fixes in crypt.c (Ed)
- 8. Add new error code ZE_UNSUP for unsupported compiler options.  Add
-    check of size of zoff_t in zip.c when LARGE_FILE_SUPPORT enabled (Ed)
- 9. Changed ZE_UNSUP to ZE_COMPERR to avoid conflict with unzip (Ed)
-10. On VMS (sufficiently recent, non-VAX), DECC$ARGV_PARSE_STYLE is set
-    automatically to preserve case of the command line if the user has
-    SET PROCESS /PARSE = EXTEND.  This obviates quoting upper-case
-    options, like -V, when enabled.  VMS.C (Steven Schweda (SMS))
-11. On VMS, building with macro VMS_PRESERVE_CASE defined preserves case
-    of names in archive, instead of forcing lower-case (the former and
-    current default behavior).  VMSZIP.C (SMS)
-12. On VMS, in some of the simplest cases, ODS5 extended file name
-    escape characters ("^") are removed from names in archive.
-    VMSZIP.C (SMS)
-13. On VMS, fixed a problem in some cases with mixed-case directory
-    names, where too much of the directory hierarchy was included in the
-    path names in the archive.  VMSZIP.C (SMS)
-14. On VMS, minor changes for large file support (long -> zoff_t).
-    VMSZIP.C (SMS)
-15. On VMS, changed some structure declarations to typedefs, and
-    rearranged to simplify #if's and reduce potential name conflicts.
-    VMS.H, VMS_IM.C, VMS_PK.C (SMS)
-16. On VMS, reformed -V (/VMS) processing.  Added -VV (/VMS=ALL).
-    Removed some sign bits to accomodate files bigger than 2GB.
-    CMDLINE.C, VMS_IM.C, VMS_PK.C, ZIP.C, ZIP_CLI.CLD, ZIP_CLI.HELP,
-    ZIPUP.H (SMS)
-17. Update command line options to support -VV as distinct option (Ed)
-18. More VMS changes (SMS)
-19. Add zoff_t format function (SMS)
-20. On VMS, when -b was not used, temporary archive files were always
-    created in the current default directory, rather than in the archive
-    file destination directory.  VMS now uses its own tempname()
-    function.  FILEIO.C, VMS.C (SMS)
-21. Remove using FNMAX for path size in a few places including filetime.c
-    to avoid exceeding limit (based on fixes from Greg and others) (Ed)
-22. Add port atheos (Ruslan Nickolaev, Ed)
-23. Bug fix adds different extra fields for local and central in VMS (SMS)
-24. Now short options also take optional values as next argument (Ed)
-25. Change -dd to control -v dots (SMS, Ed)
-26. On VMS, a new open callback function senses (where supported) the
-    process RMS_DEFAULT values for file extend quantity (deq),
-    multi-block count (mbc), and multi-buffer count (mbf), and sets the
-    FAB/RAB parameters accordingly.  The default deq is now much larger
-    than before (16384, was none), and the default mbc is now 127
-    (up from 64), speeding creation of a large archive file.  Explicitly
-    set RMS_DEFAULT values override built-in defaults.  OSDEP.H, VMS.C
-    (SMS)
-27. VMS CLI definitions and CLI help have been updated, and may be
-    approximately correct.  CMDLINE.C, ZIP_CLI.CLD, ZIP_CLI.HELP (SMS)
-28. The man file zip.1 updated and Makefile updated to generate manual
-    pages for zipcloak.1, zipnote.1, and zipsplit.1 (Ed)
----------------------- July 23rd 2005 version 3.0e ----------------------
- 1. Debian patch 004 - apply 2.4i configure changes from Onno to remove
-    need for -fno-builtin in unix/configure (Onno, Ed)
- 2. Debian patch 005 for bug 279867 - fix bug that could crash on large paths
-    and create security problem.  Apply patch changes from Greg (Greg, Ed)
- 3. SourceForge patch 1074363 - add win32i64.c to win32/makefile.w32 (Ed)
- 4. Add check when not ZIP64_SUPPORT in scanzipf_reg() in zipfile.c if
-    Zip64 archive being read (Ed)
- 5. Renamed fzofft() used to format zoff_t values to zip_fzofft() to remove
-    conflict when combined with UnZip in WiZ (Mike)
- 6. Add check in scanzipf_reg() in zipfile.c if Zip64 archive being read (Ed)
- 7. Fixes for amiga/makefile.azt to define directory for object files (Paul)
- 8. Define prototypes for local functions optionerr, get_shortopt and
-    get_longopt in fileio.c.  Define err argument of optionerr as ZCONST (Paul)
- 9. Add help_extended and DisplayRunningStats prototypes, fix other prototypes
-    in zip.c (Paul)
-10. Split int kk off of k for argument types (Paul)
-11. Aztec #endif quirk fix in zip.c for Amiga (Paul)
-12. Add detection of binary in first buffer read from file in zipup.c to avoid
-    a -l or -ll translation on binary file.  Not perfect but at least should
-    catch some binary files (Ed)
-13. Remove check for >= 128 from binary check in zipup.c as <= 6 enough for
-    signed char (SMS, Ed)
-14. SF Bug 1074368 - check for empty zip file in readzipfile() in zipfile.c
-    (Christian d'Heureuse, Ed)
-15. Add error exit to prevent archive corruption when updating a large-file
-    archive with a small-file program.  Add ZE_ZIP64 error.
-    ziperr.h, zipfile.c (SMS)
-16. Change percent() in zipup.c to do rounding better, handle cases near limits
-    while rounding, and allow negative percent returns (SMS, Ed)
-17. Add function ffile_size() in zipfile.c but in #if 0 block until determine
-    if works on all ports under all conditions.  Currently only used for size
-    check for Zip64 archive detection if compiled without ZIP64_SUPPORT and
-    this check may already be handled in scanzipf_reg() and should be added to
-    scanzipf_fix() when that is updated (SMS, Ed)
-18. Change >>1 to /2 in zipsplit.c to allow for negative percent returns (SMS)
-19. Add type uzoff_t for unsigned zoff_t things.  Should clean up some casting
-    (Ed)
-20. Based on discussions with other development groups, when data descriptors
-    (extended local headers) are used, force to Zip64.  This is compatible
-    with other unzips and does not require a change of the AppNote, but the
-    resulting archive requires Zip64 to read.  Using standard data descriptors
-    would mean that the zip operation would fail if a Zip64 entry was
-    encountered.  See zipfile.c (Ed)
-21. Add define SPLIT_SUPPORT to enable splits.  The command line options are
-    done and the globals are set up but nothing more.  globals.c, zip.h, and
-    zip.c mainly (Ed)
-22. Create spanning signature at beginning of archive when splitting enabled.
-    If reading a split archive skip the spanning signature unless creating a
-    split archive.  zip.c, globals.c (Ed)
-23. Start implementing split archives.  Define two methods. split_method = 1
-    updates local headers and is the most compatible but requires updating
-    previous splits.  split_method = 2 uses data descriptors and should work
-    for streams and removable media but may not be as compatible with other
-    zip applications.  (In part based on previous discussions with Rainer.)
-    Updated global variables to include bytes written to just the current
-    entry in the current split.  zipfile.c (Ed)
-24. Add note about output redirection to zip.1 (?, Ed)
-25. Remove num < 0 check as num now unsigned.  util.c (SMS, Ed)
-26. Change lastchar to lastchr in fileio.c in places to avoid function by same
-    name (SMS, Ed)
-27. Moved #endif /* !WINDLL */ in zip.c (Mike)
-28. Account for vms directory version being ;1.  vmszip.c (SMS)
-29. Fix Zip64 check in scanzipf_reg to use the buffer.  zipfile.c (Ed)
-30. Default define size_t (for use by Steve's ffile_size() function).  tailor.h (Ed)
-31. Enable Steve's ffile_size() function and enable large file check.  It
-    currently does not allow file sizes over 2 GB but the code is not supporting
-    it anyway without large file support.  Should remove that part of the check
-    when the casts are fixed.  zipfile.c (Ed)
-32. Fixes for djgpp.  Now compiles with djgpp 2 (Ed)
-33. Add new VC6 projects for win32 and windll (Cosmin)
-34. Convert some variables in zipsplit.c from ulg to zoff_t so compiles (Ed)
-35. Add wildcards to extended help.  zip.c (Ed)
-36. For optional option value now '-' is same as missing value.  fileio.c (Ed)
-37. Remove extra free() from -dd option switch.  zip.c (Ed)
-38. Change write_unsigned_to_mem() to write_ulong_to_mem() and write_short_to_mem()
-    to write_ushort_to_mem().  zipfile.c (Ed)
-39. Create new append to mem functions.  zipfile.c (Ed)
-40. Change zlist nam and ext from extent to ushort as that is what gets written.
-    zipfile.c (Ed)
-41. Change GetSD to use ush instead of size_t.  win32/win32zip.c (Ed)
-42. Change PutLocal(), PutExtended(), PutCentral(), and PutEnd() to write to
-    memory and then write the block at once to the file.  zipfile.c (Ed)
-43. Change zcomlen from extent to ush, other extent conversions.  zipfile.c,
-    globals.c, zip.h (Ed)
-44. Add is_seekable() and global output_is_seekable.  Do seekable check
-    when output file is opened.  zipup.c, globals.c, zip.h, zip.c (Ed)
-45. Do not increment files_so_far and bytes_so_far if file could not be read.
-    zip.c (Ed)
-46. If force_zip64 set, only force compressed size in central directory to Zip64
-    instead of all entries (csize, usize, off, disk) in Zip64 extra field.  This
-    fixes inconsistent handling of disk numbers.  zipfile.c (Ed)
-47. Add end status if displaying running stats and not all files were read.
-    zip.c (Ed)
-48. Change force_zip64 to zip64_archive in putend().  zipfile.c (Ed)
-49. Enable the i686-optimized code by default.  crc_i386.S,
-    win32/crc_i386.asm, win32/crc_i386.c (Cosmin)
-50. Document and implement a new text detection scheme provided by Cosmin in
-    set_file_type().  Should be able to handle UTF-8 and some other character sets.
-    proginfo/txtvsbin.txt, trees.c (Cosmin, Johnny, Christian)
-51. Update binary detection for -l and -ll to use Cosmin black list.  zipup.c (Ed)
-52. Change ZE_BIG to include read and write.  ziperr.h (Ed)
-53. If archive not seekable then use data descriptors.  If ZIP64_SUPPORT always
-    create Zip64 data descriptors and add a Zip64 extra field to flag it is
-    a Zip64 data descriptor.  This is klugy but should be compatible with other
-    unzips.  See the note in zipfile.c for details.  (Ed)

-     Found that using -dd with an optional value got confusing as detection
-     of an optional argument, when the next argument was not either an option
-     or the end of the line, was easy to overlook.  Easier to avoid optional
-     values.  zip.c (Ed)

-151. Fix bug where local and central headers were not matching when compiled
-     with NO_LARGE_FILE_SUPPORT.  Restored order of zlist structure elements
-     to match order of local header as scanzipf_reg() compares it as an
-     array of bytes to the local header.  Gag.  It needs fixing but at least
-     it works as intended now.  zip.h, zipfile.c (Ed)
-152. Minor fix from 10000 to 10 K for WriteNumString().  util.c (Ed)

-     negative of bytes_to_go.  This can happen if files grow in size after all
-     the sizes are initially added up.  zip.c (Ed)
-168. Use usize from filetime for adding to bytes_total when updating instead
-     of size in old entry.  zip.c (Ed)
-169. Change status counts files_so_far and bytes_so_far to include bad files
-     so the status counts end at the end but add bad_files_so_far and
-     bad_bytes_so_far to track bad files.  After minor fixes it looks like
-     the counts remaining at the end are correct, even when some files are
-     not readable.  Update bad file warnings.  zip.c, zip.h, globals.c,
-     zipup.c (Ed)
-170. Add uq for unsigned q in zipup().  Initialize z->len in case an error

-171. Check noisy in DisplayRunningStats() so logging is independent of it.
-     zip.c (Ed)

-     user.  zip.c, msdos/msdos.c, msdos/osdep.h (Johnny)
-173. Add errno.h for strerror(errno) call.  zip.c, zipup.c (SMS)
-174. Fix log problem if using -q option.  zipup.c (Ed)
-175. Change "Far char" to "char Far" as Far is a qualifier not for the char
-     type but the storage allocation of the array.  fileio.c (Christian)
-176. Update note on extent.  globals.c (Christian, Ed)
-177. Remove extra USE_ZLIB.  zip.c (Christian)
-178. Add note for the OEM_RUSS '/' bug.  Need to look at later as it seems
-     the Russian bug remains unfixed.  zipfile.c (Christian, Ed)
-180. So byte counts always come out even, create good_bytes_so_far to
-     count bytes read in and convert bytes_so_far to use the counts
-     from the initial scan.  If files change during the zip operation
-     good_bytes_so_far will change and not match bytes_so_far.
-     zip.h, globals.c, zip.c (Ed)
-181. Changes to extended help.  zip.c (Ed)
-182. Update WhatsNew (Ed)
-183. Update DLL resource copyright.  windll.rc, windll.aps (Ed)
-184. Add directory search improvements to Win32 (within recursion, reuse
-     attribs from directory lookup to avoid calling stat()).  Add
-     getd_attribs(), procname_win32().  win32/win32zip.c (Johnny)
-185. Cache result of IsFileSystemOldFAT() to avoid repetitive system calls
-     for identical information.  win32/win32.c  (Johnny)
-186. Add optimization to dosmatch(): apply alternate shortcut code when the
-     pattern to match consists of one multichar wildcard ('*') followed
-     by a fixed string.  util.c (Johnny)
-187. Move DOS check_for_windows() checks to Help and Version and errors
-     only.  Shorten message to one line.  zip.c, msdos/msdos.c (Ed)
-188. Define WIN32_OEM to enable oem ansi conversions for more than RSXNT.
-     Not yet fully implemented.  win32/win32.c, win32zip.c, zip.c,
-     zipfile.c (Ed)
-189. Directory search improvements for MSDOS.  msdos/msdos.c (Johnny)
-190. Add caching of directory information.  If pattern is just *string no
-     need to recurse.  win32/win32.c (Johnny)
-191. If wild_stop_at_dir then do recurse to handle cases like a/b/*.txt.
-     win32/win32.c (Ed)
-192. Additional improvements to directory search speedups, including
-     a) MSDOS port fixes for Turbo C++ compiler
-     b) In both Win32 and MSDOS, change getDirEntryAttr() into macro,
-        saving one function call overhead
-     e) Add explaining comment to optimized procname_{local} code
-     f) In util.c, move "*literal" pattern-matching optimization from
-        dosmatch() to recmatch(). Advantages:
-        - optimization used for all systems
-        - optimization applied to all occurences where a "*" is last wildcard
-          in pattern
-        - "dosmatch()" only preconditoning wrapper for matching workhorse
-          "recmatch()", it should not implement matching algorithms itself
-        - optimization not applied for WILD_STOP_AT_DIR option
-     g) >>>disabled<<< "*literal" optimization for all MBCS-aware environments,
-        because suspect that supplied optimization code is not MBCS-clean
-        (for details see the comment within the patch), so IS NOT USED for
-        win32 port!  Can force activation of match optimization by specifying
-        conditional compilation symbol TEST_FOR_MBCS_CLEAN.
-     (Christian)
-193. Add and move comments, implement changes for directory search improvements
-     in Zip 3.0 util.c (Ed)

-     and on AIX 4.2.0. AIX 5.1 with gcc-3.4.3 (32-bit) and Darwin built fine
-     - though AIX 5.1 needed CC=gcc make -e ... to find gcc.  According to the
-     HP-UX man page -Ae is equivalent to -Aa -D_HPUX_SOURCE +e it seems the
-     +e is needed and -Ae is more terse anyway."  Expression generated before
-     was too long.  unix/configure (Rodney Brown)
-199. Add support for osf4.0f that does not have fseeko or ftello but has 64-bit

-    - Moved some defines out of ZIP64 section.  zipfile.c
-    - Add define UTF8_PATH_EF_TAG for Unicode Path extra field.  Currently
-      the tag is 0x7075 which is 'u' 'p' for Unicode path and seems
-      free according to the AppNote.  The extra field is
-        tag (2 bytes 'u' 'p')
-        size (2 bytes)
-        Unicode Path size (2 bytes)
-        unused (2 bytes set to 0)
-        unused (2 bytes set to 0)
-        Unicode path (variable)
-      The unused locations also serve as a check in case the tag is in
-      use already.
-    - Add add_Unicode_Path_local_extra_field() and
-      add_Unicode_Path_cen_extra_field() functions. zipfile.c
-    - Add read_Unicode_Path_entry() function. zipfile.c
-    - Set uname and oname in scanzipf_ref(). zipfile.c
-    - Add define wide_to_mb_default.  Add zchar but not used. win32/osdep.h
-    - Add wide command line reading but don't use. win32/win32.c
-    - Add port functions for Unicode, including local_to_utf8_string(),
-      wide_to_escape_string() (for converting a wide character that can't be
-      converted to mb in the local character set to a reversable escape string),
-      escape_string_to_wide(), wide_to_local_string(), local_to_display_string()
-      (for creating the display version of name), utf8_to_local_string(),
-      local_to_wide_string(), wide_to_utf8_string() (NOT IMPLEMENTED), and
-      utf8_to_wide_string() (NOT IMPLEMENTED).  win32/win32.c
-    - Implement attempt at escape function.  Whenever a wide character can't
-      be mapped to the local character set, this function gets called.
-      Currently the wide character is converted to a string of hex digits.
-      If the wide can fit in 2 bytes then the form #1234 is used.  If not,
-      the 4-byte form #L12345678 is used.
-    It compiles but needs the utf8 functions implemented.  Also needs testing
-    in a multi-byte environment and only Windows is implemented so need to at
-    least do Unix. (Ed)
-17. Update freeup() to include uname and oname.  zip.c
-18. Move define wide_to_mb_default so default for all is '_'. zip.h (Ed)
-19. No changes needed to osdep.h and update unix/unix.c but not tested. (Ed)
----------------------- October 19th 2005 version 3.0f02 ----------------------
- 1. Remove null value check for split_size as get_option() already checks.
-    zip.c (Ed)
- 2. Update f$search().  vms/descrip.mms (SMS)
- 3. Save parse name before search and use that on failure.  Change name parsing
-    in ziptyp() to solve a problem with search-list logical name device directory
-    specs.  vms/vms.c (SMS)
- 4. Compile in UNICODE_SUPPORT if have wchar_t and mbstowcs().  unix/configure (Ed)
- 5. Move Unicode defines to zip.h and functions to fileio.c so generic.  Create
-    a new OEM function for Windows.  fileio.c, zip.h, tailor.h, win32/win32.c (Ed)
- 6. Add UTF-8 functions.  fileio.c (Paul)
- 7. Convert Unicode functions to use zwchar defined as unsigned long for wide
-    char.  fileio.c, zip.h (Ed)
- 8. Add wchar_t check for Unix.  unix/configure (Ed)
- 9. Add default when zwchar (4 bytes) is too big for wchar_t (2 bytes).  zip.h (Ed)
-10. Allow for states for wide characters but surrogates not done.  fileio.c (Ed)
-11. Update WhatsNew (Ed)
----------------------- December 16th 2005 version 3.0f03 ----------------------
- 1. Fix broke encryption when ZIP64_SUPPORT enabled by accounting for need for
-    data description when encrypting.  Data description is not required for
-    encryption (WinZip does not use one) but seems needed by Zip for some reason.
-    zipfile.c (Ed)
- 2. Add function bfwrite() to do buffered fwrite().  Most output already is
-    written by zfwrite used by crypt.c which now calls bfwrite.  All splitting
-    and new byte counts are done in bfwrite.  fileio.c (Ed)
- 3. Move some functions out of ZIP64_SUPPORT defines for use with UNICODE_SUPPORT.
-    zipfile.c, zip.h (Ed)
- 4. Add is_ascii_string() and only create Unicode extra field if z->iname is
-    not ascii.  zipfile.c, zip.h, fileio.c,  (Ed)
- 5. Add parameter rewrite to putlocal() to note when rewriting bytes so the bytes
-    rewritten are not counted in output totals.  zipfile.c, zip.h (Ed)
- 6. Handle VMS ... wildcard.  util.c (SMS)
- 7. Make tempzip file name global.  zip.c, globals.c, zip.h (Ed)
- 8. Add out_path global and -O path option to allow the output archive to have a
-    different name than the input archive, if there is one.  This allows
-    updating a split archive, since output to the same split name would otherwise
-    be complicated and not user friendly.  Use out_path for output.  zip.h,
-    zip.c, globals.c (Ed)
- 9. Many output functions that had output file y as parameter, such as zipup(),
-    zipcopy(), putlocal(), putcentral(), and putend(), now do not as y is
-    now global.  This allows changing y as splits are created.  zip.c (Ed)
-10. Add function zipmessage() for writing messages like zipwarn() but are
-    informational.  zip.c (Ed)
-11. Minor changes to help.  zip.c (Ed)
-12. Add SPLIT_SUPPORT to version output.  zip.c (Ed)

-14. Add set_filetype() to set attributes of split.  zip.c (Ed)
-15. Change variable a (holds attributes) to zipfile_attributes and make global.
-    zip.c, zip.h, globals.c (Ed)
-16. Add key_needed flag for encryption and move setting key to after
-    command line processed.  zip.c (SMS)
-17. Initialize dot size using default only if dot_size not set.  zip.c (Ed)
-18. Change command line processing so that last -P or -e is used.  zip.c
-    (Ed)
-19. Fix broke writing of 4-byte spanning signature at the beginning of the archive
-    if splitting.  zip.c (Ed)
-20. Use bfcopy() instead of fcopy() to copy archive beginning.  bfcopy() uses
-    global y.  zip.c (Ed)
-21. It looks like tempzf is no longer used.  zip.c (Ed)
-22. Account for SUNPRO_C and DECC_VER.  Change SPARC to Sparc.  unix/unix.c (SMS)
-23. Remove GNUC.  vms/cmdline.c (SMS)
-24. Change case of system calls.  vms/vms.c (SMS)
-25. Add fix for VMS ... matching, but may change Zip to avoid ex2in() and in2ex()
-    for pattern matching in future.  vms/vmszip.c (SMS)
-26. Remove /NODIRNAMES and /DIRNAMES from VMS help.  vms/zip_cli.help (SMS)
-27. Define new globals zip64_eocd_disk, zip64_eocd_offset, current_local_tempname,
-    bytes_this_split, and bytes_this_entry for splits.  globals.c, zip.h (Ed)
-28. Add SUNPRO C and DEC C compile checks.  unix/configure (SMS)
-29. Add CFLAGS_NOOPT for removing optimization for configure.  unix/Makefile (SMS)
-30. Modify crypthead() to use bfwrite().  crypt.h, crypt.c (Ed)
-31. Modify zfwrite() to use global output file.  crypt.h, crypt.c (Ed)
-32. Modify zfwrite() when no encryption to use bfwrite().  crypt.h (Ed)
-33. Add bfcopy() to copy to y.  fileio.c (Ed)
-34. Add close_split() and bfwrite() for splits.  fileio.c (Ed)
-35. Add is_ascii_string() to check if UTF-8 extra field is needed.  fileio.c (Ed)
-36. Change Unicode escape of 2-byte wide from #1234 to #U1234.  fileio.c (Ed)
-37. Add read_Unicode_Path_entry() to read the UTF-8 path extra field.  zipfile.c (Ed)
-38. Latest Unicode Path extra field format is
-      1 byte     Version of Unicode Path Extra Field
-      2 bytes    Name Field Checksum
-      variable   UTF-8 Version of Name
-39. Use CRC-32 for Unicode Path Checksum and AND halves.  zipfile.c (Paul)
-40. Add Unicode Path Checksum check to make sure extra field applies to Name field
-    still.  zipfile.c (Christian)
-41. Move get_extra_field() out of Zip64 block and make available for splits.
-    zipfile.c (Ed)
-42. Check in putlocal() using is_ascii_string() and don't create Unicode path
-    extra field if name is ASCII characters.  zipfile.c (Ed)
-43. If local header for split is on another disk and using split method 1, close
-    that split in putlocal() after rewrite local header.  zipfile.c (Ed)
-44. Fix data descriptor bug when encrypting where putextended() did not handle the
-    not Zip64 case, which mostly only happens now for encryption.  zipfile.c (Ed)
-45. Check for ASCII name using is_ascii_string() in putcentral() for Unicode path
-    extra field.  zipfile.c (Ed)
-46. Instead of single disk values, update putend() to use real split values for
-    current_disk, cd-start_disk, cd_entries_this_disk, cd_start_offset,
-    zip64_eocd_disk, zip64_eocd_offset, and current_disk and allow for
-    needing Zip64 if exceed standard max values for current_disk, cd_start_disk,
-    cd_entries_this_disk, total_cd_entries, and cd_start_offset.  zipfile.c (Ed)
-47. Use current_local_offset and current_local_disk for z->off and z->dsk in
-    zipup().  zipup.c (Ed)
-48. Fix bug where force_zip64 was used to determine descriptor size but can have
-    Zip64 entry without force_zip64 so use zip64_entry.  zipup.c (Ed)
-49. Change the p - o != s compression size test for splits to bytes_this_entry
-    != (key ? s + 12 : s) and avoid ftell() in split.  zipup.c (Ed)
-50. If local header is on a previous split and split method 1 do the seek on that
-    split to update header.  zipup.c (Ed)
-51. For streaming, only force Zip64 if reading stdin and writing a non-seekable
-    device.  In other cases can detect either the input file size and set Zip64
-    if needed or seek in the output to update the local headers.  zipup.c,
-    zipfile.c, zipup.c (Ed)
-52. Allow creation of stored archives with descriptors for testing.  Currently
-    they can't reliably be read but this is planned.  zipup.c, zipfile.c, zip.c
-    (Ed)
-53. Update help, adding in -e, -P, -s splitsize, -sp, and -sv options.  zip.c (Ed)
-54. Spelling fix in zipsplit man page.  man/zipsplit.1, zipsplit.txt (Ed)
-55. New option -sv and variable noisy_splits to enable verbose splitting.
-    Default is to quietly create splits, unless -sp set to pause between splits.
-    zip.h, zip.c, globals.c, fileio.c (Ed)
----------------------- December 23rd 2005 version 3.0f04 ----------------------

- 4. Change formatting of zipmessage() to remove tabbing and add formatting
-    to call to zipmessage().  fileio.c, zip.c (Ed)
- 5. Initialize many variables such as y and tempzip.  zip.c, fileio.c,
-    zipfile.c (Ed)
- 6. Add loop to pause during split method 2 to allow changing disk or changing
-    the path for the next split.  fileio.c (Ed)
- 7. If after starting new split there is not enough room for the remaining buffer
-    for split method 1 display error and exit and for split method 2 we can
-    display a warning and user can replace disk or change path.  fileio.c (Ed)
- 8. Add list to store input file arguments using add_name() to add the name to
-    filelist_struc filelist and then process the names after the input archive
-    is read.  zip.c (Ed)
- 9. Fix infinite loop when opening a log file whose name contains multiple '/'.
-    zip.c (Cosmin)
-10. Move split size message lower and only output if option sv sets
-    noisy splits.  zip.c (Ed)

-12. Add code for not SPLIT_SUPPORT case.  zipfile.c, zipup.c (Ed)
-13. Prepend '-' to commands from target clean.
-    win32/makefile.w32, win32/makenoas.w32, win32/makefile.bor (Cosmin)
-14. Must not call putenv() in iz_w32_prepareTZenv() under Cygwin.
-    win32/osdep.h (Cosmin)
-15. Add browse info in Visual C++ 6 project.  win32/vc6/zip*.dsp (Cosmin)
----------------------- December 27th 2005 version 3.0f05 ----------------------
- 1. Add proposed changes to License (Ed)

-    buffer pointer.  Fix was left out of last beta.  zipup.c (Cosmin)
- 3. Fix get_split_path() parameter.  zip.h (SMS, Ed)
- 4. Add -dg and display_globaldots to display dots globally for entire archive
-    instead of for each file.  Is not affected by noisy flag.  globals.c,
-    zip.h, zip.c, zipup.c, fileio.c (Ed)
- 5. Make dot_count and dot_size uzoff_t, dot_count because with global dots
-    dot_count does not reset and with terabyte files the number of buffers
-    could exceed 2G, dot_size to allow use of ReadNumString() to read number.
-    zip.c, zip.h, globals.c (Ed)
- 6. Add Deletion to help.  zip.c (Ed)

-    negative flag values.  globals.c, zip.h (SMS, Ed)
- 2. Remove file parameter to bfwrite() in putend().  zipfile.c (SMS, Ed)
- 3. Add back code for not SPLIT_SUPPORT to putend().  zipfile.c (SMS, Ed)
- 4. Change tag from ush to ulg in remove_local_extra_field() and
-    remove_central_extra_field() to avoid parameter problems.  zipfile.c (Ed)
- 5. Add allow_empty_archive to flag when want to create an empty archive.
-    globals.c, zip.h (Ed)
- 6. Set allow_empty_archive when using -i and expecting an archive to be
-    created.  This is in response to the 2/14/05 email.  zip.c (Ed)
- 7. Make before and after variables that hold the dates of files to
-    process or delete global so can use them in scanzipf_regnew().  zip.h,
-    zip.c, globals.c (Ed)
- 8. Change scanzipf_regnew() to be based on scanzipf_fix() which seems closer.
-    Still have not coded the new regular zipfile reader.  zipfile.c (Ed)
- 9. For new reader first get add list and then read old archive and filter
-    as reading old entries.  zip.c, zipfile.c (Ed)
-10. Define USE_NEW_READ to turn on using new reader, which is being
-    created.  This allows all to work while the new reader is being worked
-    on.  zip.c, zipfile.c (Ed)
----------------------- January 9th 2006 version 3.0f07 ----------------------
- 1. Remove dest parameter from crypthead() and zipcopy().  crypt.c (SMS, Ed)
- 2. Change -ds to handle dots for as small as every 32 KB.  zip.c (Ed)
- 3. Add ask_for_split_write_path() and ask_for_split_read_path()  for
-    asking where to put the next write split and for locating the next
-    read split.  zip.h, fileio.c (Ed)
- 4. Add in_path to track where reading splits from. zip.h, globals.c, zip.c (Ed)
- 5. Update copyright date on changed files to include 2006 (Ed)
- 6. Replace stderr with mesg for most output messages.  deflate.c, fileio.c,
-    trees.c, util.c, zip.c, zipcloak.c, zipfile.c, zipnote.c, zipsplit.c
- 7. Add mesg_line_started to track if need new line on mesg output and update
-    zipmessage() and zipwarn() to use it.  Set mesg_line_started to 1 when
-    newline not last character written to mesg and 0 when it is.  deflate.c,
-    zip.h, zip.c, globals.c, zipup(), fileio.c (Ed)
- 8. Include base_path as parameter for get_split_path().  fileio.c (Ed)
- 9. Account for VMS version in split path.  Add vms_file_version().  fileio.c,
-    zip.c, vms/vms.c, vms/vms.h (SMS)
-10. Create crc16f() to create ANDed halves crc32 for Unicode using copy
-    of crc32() but may change to use main copy.  zipfile.c, zip.h,
-    fileio.c (Ed)
-11. Close in_path and out_path in finish() and ziperr().  zip.c (Ed)
-12. Change perror() to strerror() and print to mesg in ziperr().  zip.c (Ed)

-    zipfile reader to open and close files as goes through splits.
-    zipfile.c (Ed)
-18. Change -s to default to MB and set minimum split size to 64k.
-    zip.c (Ed)

-20. Remove unused Z64_EFPos.  globals.c (Ed)
----------------------- February 13th 2006 version 3.0f08 ----------------------
- 1. Move option checks before any work is done.  zip.c (Ed)
- 2. Update bfcopy() to handle reading splits and remove input file
-    parameter and use global in_file.  fileio.c (Ed)
- 3. Change ask_for_split_read_path() to allow user aborting.  fileio.c (Ed)
- 4. Change get_split_path() to use standard file extensions from most
-    recent AppNote of .z01, .z02, ..., .z99, .z100, .z101, ... fileio.c (Ed)
- 5. Change is_ascii_string to use 0x7F for ASCII detection.  fileio.c (Ed)
- 6. Add copy_only global for when -O is used to change the format of an
-    archive without changing the contents.  This allows for converting an
-    archive to a split archive for instance.  The global copy_only is used
-    to output status information for copies when normally copied files
-    have no status messages.  globals.c (Ed)
- 7. Add in_file, split_path, total_disks, current_in_disk, and
-    current_in_offset as globals to track reading splits.  zip.h,
-    globals.c (Ed)
- 8. Update copyright date.  revision.h (Ed)
- 9. Close in_file if open in finish().  zip.c (Ed)
-10. Add -O (big o) to extended help.  zip.c (Ed)
-11. Remove readzipfile() from zipstdout() and use main call later down.
-    zip.c (Ed)
-12. Move archive reading and file scanning after command line checks.
-    zip.c (Ed)
-13. If -O out_zip and so have_out is set then set copy_only and allow
-    copying instead of error message *Nothing to do*.  zip.c (Ed)
-14. If zipbeg is just 4 bytes and spanning then assume is spanning
-    signature and set zipbeg to 0 to ignore.  zip.c (Ed)
-15. Don't open initial write test as modify if have_out is set and so have
-    a separate output file.  zip.c (Ed)
-16. If zipbeg is 0 and nothing at beginning of archive to copy then don't
-    open input file until zipcopy() does.  zip.c (Ed)
-17. If stuff at beginning then copy and close input file.  Should be able
-    to keep it open but easier to close it and let zipcopy() reopen it.
-    zip.c (Ed)
-18. Add status message when copy_only set so something is displayed.
-    zip.c (Ed)
-19. Instead of closing x at bottom close in_file.  The variable x was used
-    inconsistently and it seemed easier to make in_file global instead.
-    Then again y remains the global output variable.  zip.c (Ed)
-20. Update copyright.  zipnote.c, zipsplit.c, zipcloak.c (Ed)
-21. Change adjust_zip_local_entry() to return 1 if the entry is Zip64 and
-    0 if not.  This is needed to know how large the extended local header
-    is later.  zipfile.c (Ed)
-22. Add read_Unicode_Path_local_entry() to read the local version of the
-    Unicode Path extra field.  zipfile.c (Ed)
-23. Handle disk in adjust_zip_central_entry().  zipfile.c (Ed)
-24. Change USE_NEW_READ to SPLIT_SUPPORT as splits seems to be stable more
-    or less.  zipfile.c (Ed)
-25. Add is_signature() to compate signatures.  zipfile.c (Ed)
-26. Create scanzipf_fixnew().  It should look like scanzipf_regnew().
-    zipfile.c (Ed)
-27. Change scanzipf_regnew() to read the central directory and create zlist
-    and handle reading traditionally.  Allows using central directory
-    information, in particular file sizes, in zipcopy() while reading
-    entries.  Use global in_file instead of f for input file and set to NULL
-    when not a valid file so finish() only tries to close it if needed.
-    Check to make sure the End Of Central Directory record found is infact
-    the last one in case a stored archive is in the last 64 KB.  Refuse
-    to update a split archive but recommend using -O instead.  zipfile.c (Ed)
-28. Change readable check in readzipfile() to require input archive to exist
-    if using -O out_archive.  zipfile.c (Ed)
-29. Change putlocal() to not create a Zip64 extra field unless needed and
-    on rewriting the local header to remove Zip64 extra field if was created
-    but not needed.  Add check if assumed entry does not need Zip64 but does,
-    meaning probably the uncompressed size is less than 4 GB but the
-    compressed size is over 4 GB.  zipfile.c (Ed)
-30. Change zipcopy() to use the global in_file and y files and to open and
-    close read splits as needed.  Checks the local header against the
-    central directory header to verify same file, which should be as using
-    the disk and offset values from the central directory.  Update disk and
-    offset in central directory.  zipfile.c (Ed)
-31. Change out_path and out_len to base_path and base_len in
-    get_split_path().  fileio.c (SMS)
-32. Update command line options for VMS to include verbose splitting.
-    vms/zip_cli.cmd, vms/cmdline.c (SMS)
-33. Handle HP.  unix/unix.c (SMS)
-34. Add adler16() checksum function.  util.c (Cosmin)
-35. Use FILE_FLAG_BACKUP_SEMANTICS and a less demanding access mode
-    in CreateFile() when retrieving file attributes.  Fixes a problem
-    when adding a directory entry from an NTFS or a CDFS partition
-    (i.e. one that stores timestamps using universal time), and the
-    directory timestamp is not the same daylight savings time setting.
-    The effect is an offset in the timestamp by one hour, if zip is
-    built using NT_TZBUG_WORKAROUND. The problem is not exposed,
-    however, if NO_W32TIMES_IZFIX is defined.  win32/win32.c (Cosmin)
----------------------- March 19th 2006 version 3.0f09 ----------------------
- 1. Fix encryption problem where a large file with uncompressable data
-    can cause deflate to store bad data.  See crypt.c for details.
-    Thanks to the nice people at WinZip for finding and providing the
-    details of this problem.  crypt.c (Ed)
- 2. Add note at top of Extended Help to refer to the Zip Manual.  zip.c
-    (Ed)
- 3. Update extended help for delete.  zip.c (Ed)

-    zip.c (Ed)
-13. Define split_method -1 to not allow splitting, mainly used when reading

-    split size.  Now -s=0 or -s- disables splitting.  zip.h, globals.c,
-    zip.c (Ed)
-14. Add fflush() after dots displayed.  deflate.c, fileio.c, zipup.c (Ed)
-15. Instead of assuming buffer size as 32 KB for dots, use WSIZE for
-    compressing and SBSZ for storing and calculate as dots are counted.
-    Now dot_count and dot_size are bytes instead of buffers.  Add dots
-    to Delete and Archive modes.  zip.c, zipup.c, deflate.c, fileio.c (Ed)
-16. If reading a split archive and split size has not been given, get
-    size of first split read by zipcopy(), which should be the first

-23. Add counts for internal modes Delete and Archive.  Byte counts for -db
-    remain uncompressed size for external modes, but internal modes Delete
-    and Archive now use compressed sizes as these copy that many bytes.
-    zip.c (Ed)
-24. Add check for when ftell() wraps. zipup.c (Ed)

-    and not on stdout as list can be long.  Only list totals on stdout.
-    zip.c (Ed)
-17. Create check_unzip_version().  Fix Unix check.  Zip still creates
-    the temporary archive then does the check, and if it fails
-    the archive is deleted, even if the check fails because of the wrong
-    verion of UnZip.  On Unix only 'unzip' the system version of UnZip
-    is checked, not './unzip' which would allow putting a local more
-    up to date version of UnZip in the current directory for the check.

-11. Add note for bzip2.  zip.c (Ed)
-12. Do not do seek wrap test if ftell() returns -1 as from a pipe.  Add
-    output of last ftell() and current ftell() for zipfile too big seek

-    central directory say they are.  This allows all recovered entries to
-    be complete with all central directory information.  Calculate CRC of
-    input entry and compare to CRC from central directory.  Allow skipping
-    split disks the user may not have.  Store state of output archive
-    before each local entry and data are read, allowing seeking back and
-    restoring state to skip bad entries.  fileio.c, global.c, zipfile.c,

-    '?' in the name.  These are characters in the Unicode name stored on
-    disk but not represented in the multi-byte character set used by zip
-    for the scan.  In this case, return the short name in 8.3 format so
-    directory scan can continue.  Could put the Unicode name in the Unicode
-    extra field, but not done.  Add warning when long name is replaced
-    by short name.  Not fully tested.  win32/win32zip.c, zip.h, zip.c,
-    fileio.c (Ed)

- 2. Update VMS Find Help Library code.  vms/hlp_lib_next.com (SMS)
- 3. Instead of tempname use temp_name as parameter to avoid function
-    tempname().  zipsplit.c, zipnote.c, zipcloak.c, zip.c (Ed)
- 4. If fixing archive with -FF and no EOCDR to get disk count, see if top of
-    archive has spanning signature or local header and guess if it is

- 7. If UNICODE_SUPPORT and UNIX then try to switch to UTF-8 locale to allow
-    displaying of Unicode, otherwise just get escapes.  This results in some
-    characters displaying as whitespace if needed fonts, such as East Asian,
-    are not installed.  zip.c (Ed)
- 8. If new global unicode_escape_all is set, then escape all non-ASCII
-    characters when converting Unicode file path.  This allows viewing paths
-    as escapes on Unix that would otherwise be white space.  If not set, any
-    characters that map to the current locale are returned as is.  Can only
-    display if either supported as base by the OS or fonts installed.  Set
-    using -UN=escape option.  zip.c, fileio.c, zip.h, globals.c (Ed)

-    match from long to int as the number of possible options should always fit
-    in that.  fileio.c, globals.c (Christian)

-    the next signature and that reads a byte at a time, the scan buf is only
-    used to read in the found headers.  Since we skip the extra parts of the
-    Zip64 EOCDR, all headers are a fixed size.  Remove unused variables from
-    scanzipf_fixnew().  Use ENDCOM for end comment offset.  Instead of 64 KB
-    seek back 128 KB to find EOCDR.  Use ENDOFF and ENDTOT for offsets in

- 4. Add VMS-compatible "severity" values, add new ZE_SEV_PERR define to
-    set when perror() needs to be called, add ZIPERRORS() macro, change
-    PERR() to use ZE_SEV_PERR, change ziperrors[] to new structure array
-    to hold error strings, add new VMS facility names and severity codes
-    assigned by HP to ziperrors[] array, and add new official

-    trying to write the next local header forces opening next split.  This
-    caused copying entries from one archive to another to fail if this came up.
-    Also handle case where a new split is needed while writing central directory
-    entries.  Now close last split and update pointers to point to the new
-    split.  fileio.c (Ed)

- 7. Update description of -FF to remove Assume Worst.  zip.c (Ed)
- 8. Add all_current flag that is set if all entries in archive are current and
-    skip updating archive if -FS and all entries are current.  zip.c (Ed)
- 9. Change argv[] to args[] for "try: zip" error message as message depends on
-    new argument order in args where options are now at beginning.  zip.c (Ed)
-10. For File Sync, copy entries to new archive if file time and size are the
-    same.  If verbose, output ok when copying current entries, otherwise no
-    message when current_entry.  Set all_current to 0 if an entry not marked or
-    a file not on OS as need to avoid the All Current message in these cases to
-    catch only deletions.  zip.c (Ed)

-    f->uname gets NULL and so is_ascii_string() fails with SIGSEGV.  fileio.c
-    (Willus, Ed)

-    allows -FF to work on .exe sfx files without adding .zip.  zipfile.c (Ed)
- 7. Fix bug where only backed up 20 bytes to find Z64 EOCD Locator.  Now back
-    up 24 bytes to include size of Z64 EOCD Locator signature.  This prevented
-    reading and updating archives greater than 4 GB.  zipfile.c (Ed)
- 8. If -FF on Win32 initialize wide strings namew, inamew, and znamew to NULL.
-    zipfile.c (Ed)

-    zip.c (Ed)
- 6. In GetFileMode() and GetFileModeW() when get attributes fails
-    instead of fprintf(mesg, ...) use zipwarn() so error goes in
-    log file and new lines are displayed when needed.  win32/win32.c (Ed)
- 7. In GetSD(), change cbytes from long to ulg.  Check cbytes (the
-    compressed size of the security descriptor) and issue warning if
-    the compressed security descriptor is greater than 0x7FFF (32k)
-    as the entire header this extra field is in needs to fit in the
-    64k header.  Should be a check on the running size of the header
-    so the actual space remaining is tracked.  Maybe in Zip 3.1.  If
-    cbytes OK cast to ush and store.  win32/win32zip.c (Ed)
- 8. Use zipmessage_nl() for bytes security message so new lines are
-    handled and message goes in log file.  win32/win32zip.c (Ed)

-    function would be used to allow Unicode escapes on the command line
-    without using the -UN=escape option, but the utility of this is still
-    being determined.  zipfile.c (SMS, Ed)
- 3. Remove declaration for unused bz_deflate_init().  zipup.c (SMS, Ed)
- 4. Add release announcement file, anticipating the long-awaited release.

------------------------- May 19th 2008 version 3.0h11 ----------------------
- 1. Initialize f->namew when streaming stdin to fix bug.  fileio.c (Ed)
- 2. Change force_zip64 to start as -1 as unset, then use 1 for forcing use
-    of Zip64 and 0 for disabling use of Zip64.  Add negation of -fz to
-    prevent use of Zip64 during streaming from stdin to a non-seekable
-    output where data descriptors will be used, which allows creating
-    archives with the old stream format but will fail if a large file is
-    streamed.  Default is still to force Zip64 data descriptors when

- 2. Change non existent to nonexistent.  unix/configure (SMS)
- 3. Don't output blank line when zipmessage_nl() gets passed an empty
-    string.  This removes blank lines for skipped entries when -FS used.
-    zip.c (Ed)
------------------------- May 27th 2008 version 3.0h13 ----------------------
- 1. Change UNICODE_ALLOW_FORCE to UNICODE_SUPPORT, -UN=force to -UN=UTF8,
-    and unicode_force to utf8_force.  This option now standard with Unicode
-    support and forces Zip to save UTF-8 paths and comments, when not ASCII,
-    as if UTF-8 were the native character set.  globals.c, zip.c, zip.h (Ed)
- 2. Add note to Todo that it's out of date.  TODO (Ed)

- 4. Update Unicode help in extended help.  zip.c (Ed)
- 5. Update announcements.  zip30h.ann, zip30.ann (Ed)
- 6. Fix bug with -UN=UTF8.  zip.c, zipfile.c (Ed)
- 7. Update Zip manual.  man/zip.1, zip.txt (Ed)
- 8. Attempt an update to zip limits document.  proginfo/ziplimit.txt (Ed)
- 9. Update README regarding forum postings.  README (Ed)
-10. Remove duplicate initialization lines for found and fnxt.  zip.c (SMS)
------------------------- May 28th 2008 version 3.0h14 ----------------------
- 1. Remove >= 0 check from wide character check as value is unsigned.
-    fileio.c (SMS)
- 2. In putlocal(), move nam and use_uname to UNICODE_SUPPORT block.  If
-    no UNICODE_SUPPORT use z->nam instead of nam.  zipfile.c (SMS, Ed)
- 3. Update announcement date for beta.  zip30h.ann (Ed)
------------------------- May 31st 2008 version 3.0h ------------------------
- 1. In putlocal() if using UTF-8 bit then also set UTF-8 bit in z->lflg so
-    is set in local header for streaming.  zipfile.c (Ed)
- 2. Update announcement date for beta.  zip30h.ann (Ed)
- 3. Rename lib and dll projects to zip32z64 and update project files so
-    project name is same as lib and dll libraries.  Export make files.
-    windll/visualc/dll/zip32z64.dsp, windll/visualc/dll/zip32z64.dsw,

-Zip 3.0 is the first Zip update adding large file support.  For now Zip 2.3x
-remains available and supported, but users should switch to this new release.
-
-Testing for Zip 3.0 has focused mainly on Unix, VMS, Max OS X, and Win32,
-and some other ports may not be fully supported yet.  If you find your
-favorite port is broke, send us the details or, better, send bug fixes.  It's
-possible that support for some older ports may be dropped in the future.
-

-Copyright (c) 1990-2008 Info-ZIP.  All rights reserved.
-
-See the accompanying file LICENSE (the contents of which are also included
-in unzip.h, zip.h and wiz.h) for terms of use.  If, for some reason, all
-of these files are missing, the Info-ZIP license also may be found at:
-ftp://ftp.info-zip.org/pub/infozip/license.html and
-http://www.info-zip.org/pub/infozip/license.html.
-
-
-Zip 3.0 is a compression and file packaging utility.  It is compatible with
-PKZIP 2.04g (Phil Katz ZIP) for MSDOS systems.  There is a companion to zip
-called unzip (of course) which you should be able to find in the same place
-you got zip.  See the file 'WHERE' for details on ftp sites and mail
-servers.
-
-So far zip has been ported to a wide array of Unix and other mainframes,
-minis, and micros including VMS, OS/2, Minix, MSDOS, Windows, Atari, Amiga,
-BeOS and VM/CMS.  Although highly compatible with PKware's PKZIP and PKUNZIP
-utilities of MSDOS fame, our primary objective has been one of portability
-and other-than-MSDOS functionality.  Features not found in the PKWare version
-include creation of zip files in a pipe or on a device; VMS, BeOS and OS/2
-extended file attributes; conversion from Unix to MSDOS text file format; and,
-of course, the ability to run on most of your favorite operating systems.  And
-it's free.
-
-See the file zip30.ann for a summary of new features in Zip 3.0 and WhatsNew
-for the detailed list of new features and changes since Zip 2.32.  The file
-CHANGES details all day-to-day changes during development.
-
-Notes:
-
-Multi-volume support.  This version does not support multi-volume spanned
-archives as in pkzip 2.04g, and there is no intention at this point to support
-spanned archives, but Zip 3.0 supports split archives.  A split archive is an
-archive split into a set of files, each file a piece of the archive and each
-file using an extension, such as .z02 as in the file name archive.z02, that
-provides the order of the splits.  In contrast, a spanned archive is the
-original multi-floppy archive supported by pkzip 2.0g where the split order
-is contained in the volume labels.  The contents of split and spanned archives
-are mostly identical and there is a simple procedure to convert between the
-formats.  Many current unzips now support split archives.
-
-Zip64 support.  This version supports Zip64 archives as described in the
-PKWare AppNote.  These archives use additional fields to support archives
-greater than 2 GB and files in archives over the 2 GB previous limit (4 GB
-on some ports).  The Zip64 format also allows more than 64k entries in an
-archive.  Support by the OS for files larger than 4 GB is needed for Zip to
-create and read large files and archives.  On Unix, Win32, and some other
-ports, large file and Zip64 support is automatically checked for and
-compiled in if available.  Use of Zip64 by Zip is automatic and to maximize
-backward compatibility the Zip64 fields will only be used if needed.  A
-Zip64 archive requires a pkzip 4.5 compatible unzip, such as UnZip 6.0.
-
-Unicode support.  This version has initial Unicode support.  This allows
-paths and names of files in other character sets to be accurately recreated
-on OS that have sufficient character set support.  On Win32, if wide
-character calls are supported (not Win 9x unless Unicode support has been
-added) all files (including paths with illegal characters in the current
-character set) should now be readable by zip.  Unicode support is provided
-using a new set of UTF-8 path and comment extra fields and a new UTF-8 bit
-for flagging when the current character set is already UTF-8.  Zip 3.0
-maintains backward compatibility with older archives and is mostly compliant
-with the new Unicode additions in the latest PKWare AppNote.  The exception
-is UTF-8 comments, which are not supported if UTF-8 is not the native
-character set, but should be fully implemented in Zip 3.1.
-
-16-bit OS support.  Though Zip 3.0 is designed to support the latest zip
-standards and modern OS, some effort has been made to maintain support
-for older and smaller systems.  If you find Zip 3.0 does not fit on or
-otherwise does not work well on a particular OS, send in the details and
-we might be able to help.
-
-Compression methods.  In addition to the standard store and deflate methods,
-Zip now can use the bzip2 compression format using the bzip2 library.  Though
-bzip2 compression generally takes longer, in many cases using bzip2 results
-in much better compression.  However, many unzips may not yet support
-bzip2 compressed entries in archives, so test your unzip first before using
-bzip2 compression.
-
-Installation.  Please read the file INSTALL for information on how to compile
-and install zip, zipsplit, zipcloak, and zipnote and please read the manual
-pages ZIP.txt, ZIPSPLIT.txt, ZIPCLOAK.txt, and ZIPNOTE.txt for information on
-how to use them.  Also, if you are using MSDOS or Windows, note that text
-files in the distribution are generally in Unix line end format (LF only)
-and Windows and DOS users will need to either convert the files as needed to
-DOS line ends (CR LF) or extract the distribution contents using unzip -a.
-
-Utilities.  At this point zipsplit, zipcloak, and zipnote should work with
-large files, but they currently do not handle split archives.  A work around
-is to use zip to convert a split archive to a single file archive and then use
-the utilities on that archive.
-
-Encryption.  This version supports standard zip encryption.  Until recently
-the encryption code was distributed separately because of the US export
-regulations but now is part of the main distribution.  See crypt.c for
-details.  Decryption can be made with unzip 5.0p1 or later, or with zipcloak.
-
-Bug reports.  All bug reports or patches should go to zip-bugs via the web
-site contact form at http://www.info-zip.org/zip-bug.html (we have discontinued
-the old email address zip-bugs@lists.wku.edu because of too much spam lately)
-and suggestions for new features can be submitted there also (although we don't
-promise to use all of them).  We also are on SourceForge at
-http://sourceforge.net/projects/infozip/ and now automatically get Bug Reports
-and Feature Requests submitted there.  In addition, a new Info-ZIP discussion
-forum is available as well.  See below.  Though bug reports can be posted there,
-we don't have automatic monitoring of all postings set up yet so you may want
-to use the web form or SoureForge for a quicker response.  A good approach may
-be to post the details on the forum so others can benefit from the posting,
-then use the web reply form to let us know you did that if you don't get a
-reply in a reasonable time.
-
-Ports.  If you're considering a port, please check in with zip-bugs FIRST,
-since the code is constantly being updated behind the scenes.  We'll
-arrange to give you access to the latest source.
-
-Discussion group.  If you'd like to keep up to date with our Zip (and companion
-UnZip utility) development, join the ranks of BETA testers, add your own
-thoughts and contributions, etc., check out the new discussion forum.  This is
-the latest offering, after the various Info-ZIP mailing-lists on
-mxserver@lists.wku.edu (courtesy of Hunter Goatley) were no longer available
-and the temporary QuickTopic discussion group for Info-ZIP issues at
-http://www.quicktopic.com/27/H/V6ZQZ54uKNL died a horrible death due to large
-amounts of spam.  The new discussion forum is now available at
-http://www.info-zip.org/board/board.pl (thanks again to Hunter Goatley) and
-can be used to discuss issues, request features, and is one place new betas
-and releases are announced.  It also is a place to post bug reports, and
-patches can be submitted as attachments.  However, we don't yet get
-automatic notification of all postings there so try one of the other methods
-if you don't get a response.  You can also post Bug Reports and Feature
-Requests at Source Forge.  However, the web site contact form remains
-available if you would rather not post on the public forums.
-
-Frequently asked questions on zip and unzip:
-
-Q. When unzipping I get an error message about "compression method 8".
-
-A. This is standard deflate, which has been around for awhile.  Please
-   get a current version of unzip.  See the file 'WHERE' for details.
-
-
-Q. How about "compression method 12"?
-
-A. Compression method 12 is bzip2 and requires a relatively modern unzip.
-   Please get the latest version of unzip.
-
-
-Q. I can't extract this zip file that I just downloaded.  I get
-   "zipfile is part of multi-disk archive" or some other message.
-
-A. Please make sure that you made the transfer in binary mode.  Check
-   in particular that your copy has exactly the same size as the original.
-   Note that the above message also may actually mean you have only part
-   of a multi-part archive.  Also note that UnZip 5.x does not and UnZip 6.0
-   probably won't have multi-disk (split) archive support.  A work around
-   is to use Zip 3.0 to convert the split archive to a single-file archive
-   then use UnZip on that archive.  As a last result, if there's something
-   readable in what you have, zip -FF should be able to recover it.
-
-
-Q. When running unzip, I get a message about "End-of-central-directory
-   signature not found".
-
-A. This usually means that your zip archive is damaged, or that you
-   have an uncompressed file with the same name in the same directory.
-   In the first case, it makes more sense to contact the person you
-   obtained the zip file from rather than the Info-ZIP software
-   developers, and to make sure that your copy is strictly identical to
-   the original.  In the second case, use "unzip zipfile.zip" instead
-   of "unzip zipfile", to let unzip know which file is the zip archive
-   you want to extract.
-
-
-Q. Why doesn't zip do <something> just like PKZIP does?
-
-A. Zip is not a PKZIP clone and is not intended to be one.  In some
-   cases we feel PKZIP does not do the right thing (e.g., not
-   including pathnames by default); in some cases the operating system
-   itself is responsible (e.g., under Unix it is the shell which
-   expands wildcards, not zip).  Info-ZIP's and PKWARE's zipfiles
-   are interchangeable, not the programs.
-
-   For example, if you are used to the following PKZIP command:
-               pkzip -rP foo *.c
-   you must use instead on Unix:
-               zip -R foo "*.c"
-   (the quotes are needed to let the shell know that it should
-    not expand the *.c argument but instead pass it on to the program,
-    but are not needed on ports that do not expand file paths like
-    MSDOS)
-
-
-Q. Can I distribute zip and unzip sources and/or executables?
-
-A. You may redistribute the latest official distributions without any
-   modification, without even asking us for permission. You can charge
-   for the cost of the media (CDROM, diskettes, etc...) and a small copying
-   fee.  If you want to distribute modified versions please contact us at
-   www.Info-ZIP.org first. You must not distribute beta versions.
-   The latest official distributions are always on ftp.Info-ZIP.org in
-   directory /pub/infozip and subdirectories and at SourceForge.
-
-
-Q. Can I use the executables of zip and unzip to distribute my software?
-
-A. Yes, so long as it is made clear in the product documentation that
-   zip or unzip are not being sold, that the source code is freely
-   available, and that there are no extra or hidden charges resulting
-   from its use by or inclusion with the commercial product.  See the
-   Info-ZIP license for more.  Here is an example of a suitable notice:
-
-     NOTE:  <Product> is packaged on this CD using Info-ZIP's compression
-     utility.  The installation program uses UnZip to read zip files from
-     the CD.  Info-ZIP's software (Zip, UnZip and related utilities) is
-     freely distributed under the Info-ZIP license and can be obtained as
-     source code or executables from various anonymous-ftp sites,
-     including ftp://ftp.info-zip.org/pub/infozip.
-
-
-Q. Can I use the source code of zip and unzip in my commercial application?

-_____________________________________________________________________________
-
-  This is Info-ZIP's README.CR for zcrypt29.zip, last updated 27 March 2008.
-_____________________________________________________________________________
-
-
-The files described below contain the encryption/decryption code for Zip 2.31,
-UnZip 5.52, and WiZ 5.02 (and later).  These files are included in the main
-source distributions for all of these now, but the encryption patch is still
-available for earlier versions of these.  This file both describes the history
-of the encryption package and notes the current conditions for use.  Check
-the comments at the top of crypt.c and crypt.h for additional information.
-
-As of version 2.9, this encryption source code is copyrighted by Info-ZIP;
-see the enclosed LICENSE file for details.  Older versions remain in the pub-
-lic domain.  Zcrypt was originally written in Europe and, as of April 2000,
-can be freely distributed from the US as well as other countries.
-
-(The ability to export from the US is new and is due to a change in the Bureau
-of Export Administration's regulations, as published in Volume 65, Number
-10, of the Federal Register [14 January 2000].  Info-ZIP filed the required
-notification via e-mail on 9 April 2000; see the USexport.msg file in this
-archive.  However, as of June 2002, it can now be freely distributed in both
-source and object forms from any country, including the USA under License
-Exception TSU of the U.S. Export Administration Regulations (section 740.13(e))
-of 6 June 2002.)
-
-    LIKE ANYTHING ELSE THAT IS FREE, ZIP, UNZIP AND THEIR ASSOCIATED
-    UTILITIES ARE PROVIDED AS IS AND COME WITH NO WARRANTY OF ANY KIND,
-    EITHER EXPRESSED OR IMPLIED. IN NO EVENT WILL THE AUTHORS BE LIABLE
-    FOR ANY DAMAGES RESULTING FROM THE USE OF THIS SOFTWARE.
-
-The encryption code is a direct transcription of the algorithm from
-Roger Schlafly, described by Phil Katz in the file appnote.txt.  This
-file is distributed with the PKZIP program (even in the version without
-encryption capabilities).  Note that the encryption will probably resist
-attacks by amateurs if the password is well chosen and long enough (at 
-least 8 characters) but it will probably not resist attacks by experts.
-Paul Kocher has made available information concerning a known-plaintext
-attack for the PKWARE encryption scheme; see http://www.cryptography.com/
-for details.)  Short passwords consisting of lowercase letters only can be
-recovered in a few hours on any workstation.  But for casual cryptography
-designed to keep your mother from reading your mail, it's OK.
-
-For more serious encryption, check into PGP (Pretty Good Privacy), a
-public-key-based encryption system available from various Internet sites.
-PGP has Zip and UnZip built into it.  The most recent version at the time
-this was originally written was 6.5, although older versions were still
-widespread.  At the time of this writing there are now GPG, PGP Universal
-2.0, and various others based on OpenPGP.
-
-We are looking at adding AES strong encryption to future versions of Zip and
-UnZip.
-
-Zip 2.3x and UnZip 5.5x and later are compatible with PKZIP 2.04g.  (Thanks
-to Phil Katz for accepting our suggested minor changes to the zipfile format.)
-
-IMPORTANT NOTE:
-
-  Zip archives produced by Zip 2.0 or later must not be *updated* by
-  Zip 1.1 or PKZIP 1.10 or PKZIP 1.93a, if they contain encrypted members
-  or if they have been produced in a pipe or on a non-seekable device.
-  The old versions of Zip or PKZIP would destroy the zip structure.  The
-  old versions can list the contents of the zipfile but cannot extract
-  it anyway (because of the new compression algorithm).  If you do not
-  use encryption and compress regular disk files, you need not worry about
-  this problem.
-
-
-Contents that were distributed and now are part of the main source files:
-
-  file           what it is
-  ----           ----------
-  README.CR      this file
-  LICENSE        Info-ZIP license (terms of reuse and redistribution)
-  USexport.msg   export notice sent to US Bureau of Export Administration
-  WHERE          where Zip/UnZip/WiZ and related utilities can be found
-  crypt.c        code for encryption and decryption
-  crypt.h        code for encryption and decryption
-  file_id.diz    description file for some BBSes
-
-Most all of the files are in Unix (LF only) format.  On MSDOS systems, you
-can use the -a option of UnZip to convert the source files to CRLF
-format.  This is only necessary if you wish to edit the files -- they
-will compile as is with Microsoft C and Turbo/Borland C++ 1.0 or
-later.  However, you will have to convert the files (using "unzip -a")
-to the CRLF format to compile with the older Turbo C 1.0 or 2.0.  You
-should be able to find Zip and UnZip in the same place you found this 
-(see ftp://ftp.info-zip.org/pub/infozip/Info-ZIP.html or the file
-"WHERE" for details).
-
-Current releases all have encryption built in.  To update previous versions
-using the zcrypt sources:
-
-  (1) Get the main sources (e.g., Zip 2.3) and unpack into a working
-      directory, as usual.
-
-  (2) Overwrite the dummy crypt.c and crypt.h from the main sources with 
-      the versions from this package.  If you want to overwrite directly
-      out of the zcrypt29 archive, do not use UnZip's freshen/updating
-      option; the dummy files may be newer than the real sources in
-      zcrypt29.  ("unzip -o zcrypt29 -d /your/working/dir" will do the
-      Right Thing in most cases, although it may overwrite a newer WHERE
-      file under some circumstances.)
-
-  (3) Read the main INSTALL document and compile normally!  No makefile
-      changes are necessary on account of the zcrypt sources.  You can
-      check that the version you just compiled has encryption or decryption
-      support enabled by typing "zip -v" or "unzip -v" and verifying that
-      the last "special compilation option" says encryption or decryption
-      is included.
-
-Encryption enables new "-e" and "-P password" options in Zip, and a new
-"-P password" option in UnZip--see the normal Zip and UnZip documentation
-for details.  (Note that passing a plaintext password on the command line
-is potentially much more insecure than being prompted for it interactively,
-which is the default for UnZip and for Zip with "-e".  Also note that the
-interactive method allows UnZip to deal with archives that use different
-passwords for different files.)

-Todo list (last updated 12 June 2008).
-
-Features for next official version:
-
-- Extended attributes for Windows, Linux, and Mac OS X.
-- Win32 ACL rewrite to use backup api to create new and more useful extra
-  field (need unzip support) (Kai).
-- Allow -d@ to read in a list of names to delete (11/17/2005).
-- AES encryption (3/19/05).
-
-Features that may make the next release:
-
-- Allow reading in list of files using @filename.
-- When -R, -x, or -i pattern ends in a directory add / to the end
-      (11/5/2004 Nehal).
-- Decide if -R, -i and -x should use external rather than internal patterns.
-      Also, change pattern matching to not do ex2in() and then in2ex() if
-      appropriate.  (12/26/2005 SMS)
-- Though Unicode paths have been implemented and tested, Unicode comments
-      are not yet supported (except for comments on UTF-8 native systems which
-      are supported).
-- Verbose mode -v may still need work.
-
-- Add C# example for Zip 3.0 (need to be converted to new DLLs) - original
-      C# example added with note.
-- Path Prefix maybe, so entries added to an archive can have a directory
-      path string prepended to each path so can zip multiple drives and avoid
-      name conflicts (4/17/2006).
-- UNC paths like \\server\path (4/26/2005).
-- Support for other languages maybe.
-
-- Add About page option similar to -h2 and -v but lists Info-ZIP
-      information (could be -sa) (4/29/2006).
-- Update utilities ZipSplit, ZipNote, and ZipCloak to handle split archives.
-- Update ziperr and finish if needed.
-- Review memory allocation and fill in memory leaks if any.
-- Enhance -FF to fix common problems such as archives ftp in text mode
-      and fixing checksums so entries can be extracted if that makes
-      sense (6/17/2007).
-- Add \ to / conversion in zipsplit to fix problem in
-      1/29/2004 email.
-- Encryption bug with small stored file (12/27/2005) (fixed?).
-
-- When updating large archives with few entries being
-      updated maybe display something in large periods of
-      quiet (1/23/2006).
-- Windows OEM comments (5/17/2006).
-- Example of using MVS zip and unzip (3/30/2004) (Need one).
-- UTF-8 comments need to be implemented (6/17/2007)
-- Maybe convert ../ in archive (5/20/2006).
-- Per so many buffers dll callback (12/23/2005 Ale).
-- Allow rename stdin "-" to something else (12/27/2005 gregor).
-- Check for possible buffer overrun weaknesses while reading zip files.
-- Do Active Template Library (ATL) (4/27/2005).
-- Flush Win16 support - to be determined (Mike).
-- Way to convert file names on input, converting foo.c to dir/foo_bar.c
-      for instance (4/8/2004, 3/12/2004).
-- French WiZ (not a Zip thing actually but dependent on zip and unzip).
-- Then there is that wierd ^D being converted to \000 error reported
-      in 6/21/2003 email when Zip is outputted into a pipe on Windows ports.
-
-Old list:
-
-Main features still missing for next official version (last updated 2/11/2001):
-
-- what about the binary/text detection ? (seems done)
-- -b and -t options in help screen (covered in -h2)
-- findfirst/findnext and after that LSSTAT (performance!!)
-- use IS_EXEC from djgpp stat.h
-- use install in unix/Makefile instead of mkdir -p, look at install sh script.
-- #elif for those ports that can handle it.
-- what about zopen vs. fopen ?
-- Add zcreate or zfcreate for win32.
-- Assembler stuff in match.S (subexpressions)
-- zipping huge files (> 2G, unsigned 32bit) (done)
-- Testsuite for zip and unzip (John D. Mitchell)
-- make a version.c or version.h that includes all the compiler names
-- run utils with dmalloc().
-- what to do with zip -F and zip -FF (readzipfile2()) ? (done?)
-- profiling of the code
-- multi disk zip files (could be done)
-- zipfile modification tool (Greg)
-- Implement -- option (Thomas Klauser, wiz@danbala.tuwien.ac.at) (could be done)
-- don't add files with "Archive bit" or add files with "Archive bit"
-	(uwe.becher@metronet.de) (could be done with -AS and -AC)
-- 32 bit file attributes
-- generate output without having to seek at all (this seems to be stream output)
-- remove contractions from zip error messages, make them clearer (Steve)
-- display "[text]" for ascii files when not quiet (no -q) (Timo Salmi)
-- does zipnote accept names with version number?
-- for a WORM, zip should create temp file only when updating; new archives
-	should be created directly.
-- APPNOTE.TXT specifies "4) The entries in the central directory may
-      not necessarily be in the same order that files appear in the zipfile"
-      but readzipfile() relies on same order. (new read does not, and now
-      the read for -FF searches for central directory matches rather than
-      rely on the order)
-- on Mac, MPW C 3.3.1 requires #if (a || b)  ["#if a || b" taken as "#if a"]
-- on Unix, let -S be "include non-regular files without reading from them"
-	(as pkzip on Unix). This requires unzip support.
-- zip -l should do ebcdic->ascii translation on CMS and MVS
-- zip as subroutine (zdig/241) (some work done on this)
-- accept k and M in zipsplit
-- store / (part of file name) as ! in OS/2 (problem only with -E ?)
-- in addition to -l (LF to CR LF) and -ll (CR LF to LF) add -lc
-	(LF to CR LF but CR LF remains unchanged)
-
-Known bugs:
-
-- On VMS, zip fails reading some files with "byte record too large for
-	user's buffer". You must use the "-V" option for such files.
-	(many changes to VMS so may be fixed)
-
-- on MSDOS, zip386.exe does not like "zip -bc: foo ..."
-
-- on MSDOS, zip386.exe is sometimes much slower than zip.exe. This is
-	probably a problem with DJGPP (to be investigated).
-
-- on NT with C shell, zip should not do file name expansion again.
-
-- zip zipfile ... ignores existing zipfile if name does not have an extension
-      (except for the -A option, generally used on self-extracting files).
-      (archives should probably have extensions.  Things like archive.jar work)
-
-- For an sfx file without extension, "zip -A sfx" works but "zip sfx -A"
-	doesn't.  (because options were required first, but now both OK)
-
-- When storing files in a zipfile (-0), zip marks all of them as binary.
-
-- On VMS, some indexed files are not restored correctly after zip -V and unzip.
-	(This is now known to be a problem of UnZip. The workaround for Zip 2.2
-	and newer is to use PK-style VMS extra fields; this is now the default.
-	NOTE that UnZip 5.32 has been fixed [971019]!) (many VMS changes so
-	this may be fixed)
-
-- zip and unzip should use the same pattern matching rules, particularly
-	on MSDOS and OS/2. On OS/2, "zip foo *.*" should also match files
-	without extension.
-	Partially DONE (OS/2 "*.*" matches "*".)
-
-- there should be a way to avoid updating archive members (only addition
-	of new files allowed)

-FURTHER COMMENTS:
-
-(1) This notice is being sent in order to ensure that we may legally
-    take advantage of the 6 June 2002 amendment to 740.13 regarding
-    "corresponding object code."  The encryption code in question is
-    unchanged since our original notification of 9 April 2000, appended
-    below and also reproduced within the above zcrypt.zip archive.
-    (Indeed, there has been no change to the core encryption/decryption
-    code in well over five years.)
-
-(2) The (larger) source archives for Zip, UnZip, MacZip, WiZ, and
-    potentially other packages, currently available in the same ftp
-    directory given above, also contain (or may contain) copies of
-    the same zcrypt source code.
-
-(3) ftp.info-zip.org currently points to a site in Germany, so techni-
-    cally it is not involved in "US export" in any direct way.  However,
-    we encourage other sites to "mirror" our software, and some of these
-    mirror sites may be US-based (and therefore involved in reexport of
-    the code in question).  In addition, some Info-ZIP members reside in
-    the US, and www.info-zip.org currently points to a site in Kentucky.

-What's New
-
-Last updated 1 July 2008
-
-This file is the full list of new features and major changes for Zip 3.0
-by beta release.  See the announcement file zip30.ann for a quick summary
-of all features and changes in Zip 3.0.  Also see the file README for
-release information, INSTALL for installation procedures, and the manual
-pages zip.txt, zipsplit.txt, zipcloak.txt, and zipnote.txt for how to use
-the new features.  The file CHANGES has all the day-to-day changes made
-during development.
-
-
-Below are some of the more significant items on the list for Zip 3.1
-(see ToDo for a more complete list):
-
-- AES encryption.
-- Extended attributes for Windows, Linux, and Mac OS X.
-- Support -d@ for deleting list of files.
-- Decide if -R, -i and -x should use external rather than internal patterns.
-- Though Unicode paths have been implemented and tested, Unicode comments
-  are not yet supported (except for comments on UTF-8 native systems which
-  are supported).
-- Verbose mode -v may still need work.
-- When pattern is directory add end / automatically.

-  path string prepended to each path.
-- UNC path support maybe.
-- Support for other languages maybe.
-- Send in your suggestions.

-
-
-MAJOR CHANGES BY BETA VERSION
------------------------------
-
-New things in Zip 3.0 since Zip 3.0h:
-
-- Unicode fixes.
-- Test and fix various ports as needed.
-- Update Win32 resource to support more Windows ports.
-- Add djgpp 2.x makefile that includes bzip2.
-- Add Win32 version resource to Win32 executable.
-- Bug fixes.
-- Documentation updates.
-- Package for release.
-
-
-New things in Zip 3.0h
-
-- Allow -@ and -x to work together.
-- Unicode code cleanup.
-- Allow forcing use of UTF-8 storage in standard path and comment.
-- Update symbolic link checks.
-- Add support for storing 32-bit UIDs/GIDs using new extra field.
-  Backward compatible support for the old 16-bit UID/GID extra field
-  remains if Zip is compiled on an OS that has 16-bit UID/GID
-  storage.
-- Update VMS notes.
-- Directory scan using -AS (include only files with Windows archive
-  bit set) now ignores archive bit on directories to include all files
-  with archive bit set in all directories.  Also, to avoid empty
-  directories being created, -AS now does not store directory
-  entries.
-- Add Unix IBM support.
-- Change -W to -ws to free -W for later use.
-- Fix large file support for MinGW.
-- Fix large file support for bzip2.
-- Fix compile error in ZipCloak when UNICODE_SUPPORT is not enabled.
-- Fix Unicode bug in ZipCloak involving Unicode paths.
-- Long Unicode escapes changed from #Lxxxxxxxx to #Lxxxxxx to shorten
-  paths with escaped Unicode.
-- Bug fixes.
-
-
-New things in Zip 3.0g
-
-- Add split support to VB project for Zip64.
-- Disable reading of Unix FIFOs unless new -FI option used to avoid an
-  archiving operation stopping when it hits an active unfed FIFO.
-- The "[list]" wildcard expression (regular expression matching of any
-  character or range of characters in list) is now disabled on DOS and
-  Windows as it has caused confusion when filenames have [ and ] in
-  them.  The new -RE option reenables it.
-- Add negation to many display options such as -dc and -db.
-- Allow -FF to read and fix archives having local entries that appear
-  after central directory entries.
-- Bug fixes.
-
-
-New things in Zip 3.0f
-
-- bzip2 - The bzip2 compression method looks supported for at least
-  Windows, Unix, and VMS using the bzip2 library.  A new option, -Z cm,
-  selects the compression method.
-
-- Split archives - Can now use -s to create a split archive.  The
-  default is to update split files as the archive is being written,
-  which requires all splits to remain open until the archive is done.
-  This should be no problem when writing the archive to a hard drive,
-  for example, and this approach creates archives that should be
-  supported by all unzips that support splits.  Adding the -sp option
-  enables split pause mode that instead writes splits that do not
-  need updating and pauses Zip after each split.  This allows splits
-  to be written directly to removable media, however -sp archives
-  may not be as universally compatible.
-
-- Unicode support - Zip now stores Unicode paths that should be more
-  portable across character sets and languages.  The unzip must have
-  Unicode support enabled or the Unicode paths are ignored.  If
-  reading an archive with Unicode paths, unsupported characters are
-  replaced by #Uxxxx and #Lxxxxxxxx escapes in the file name.  Option
-  -UN controls how Unicode is handled.  Also, on systems where the
-  current character set is UTF-8, preliminary support for the new
-  General Purpose Bit Flag, bit 11, UTF-8 flag, that indicates UTF-8
-  is stored in the path and comment fields is implemented for paths.
-- Unicode on Win32 - On WIN32 systems that support the wide character
-  calls (mainly NT and later systems using NTFS), when UNICODE SUPPORT
-  is enabled Zip will now do directory scans using Unicode and convert
-  the Unicode paths to the local character set for storage in the standard
-  path field and store UTF-8 in the Unicode extra field.  This allows
-  directory scans to complete successfully regardless of the character
-  set the path is in.  On Win9x systems wide character scans are not
-  generally supported and Zip automatically uses a local character scan
-  instead.
-
-- Keep extra fields option - The default operation has been, and continues
-  to be, to read then strip old extra fields when reading entries from an
-  existing archive and then recreate the extra fields that Zip knows about.
-  Extra fields specific to each operating system get added by default also.
-  The new option -X- (negated -X) keeps any old extra fields, copying
-  them to the updated archive unchanged (unless Zip has updated them).
-  The unnegated -X still strips most all extra fields except Zip64,
-  Unicode, and UT time.
-
-- License - minor updates to the license.
-
-- Windows OEM - When compiled with WIN32_OEM (the default for WIN32),
-  Zip on WIN32 now stores OEM paths, which should be more compatible
-  with other zips and should fix some character set problems.
-- Windows Archive Bit support - On Windows can now use new -AS
-  (include if archive bit set) option to select files with the DOS
-  archive bit set and use new -AC (clear archive bits) option to clear
-  the archive bits on files after the archive has been created.
-  But -DF is probably better.
-
-- Difference mode - A new option -DF (--dif) creates an output archive
-  that includes only files changed or new since the input archive was
-  created.  Can use to create incremental backups.
-- File Sync - The new option -FS enables File Sync, a new mode that
-  synchronizes the entries in an archive with the files on the file
-  system, adding updating, and deleting entries as needed.  This
-  should create the same results as creating a new archive, but
-  since existing entries are copied, may be much faster.
-
-- Copy Mode - A new --out option allows creating a new archive with a
-  different name than the input archive, leaving the input archive
-  unchanged.  This allows updating split archives.  It also allows
-  for a new copy mode to select entries in one archive and copy them
-  directly to a new archive.
-- Empty archives - Now an empty archive is created when -i or -i@ is used
-  and the file patterns given do not match anything.  This has been
-  requested to support scripts.
-
-- Global dots - A new -dg option now displays progress dots as -dd does,
-  but instead of displaying them for each file, the dots track the total
-  bytes read for the archive.  The -dg option also works when -q is used
-  to disable most output, which allows for something like zip -qdgds 100m
-  to be used to not display specific files but display a dot every 100 MB
-  as a global status.
-- Date range - Can now use -t and -tt to set a date range
-- Fix options - Option -F redone and can recover files from an archive
-  with a mostly complete central directory more reliably, but no longer
-  can handle truncated archives.  Option -FF redone and now can salvage
-  files from slightly more damaged archives, including truncated archives.
-  In some ways -F is less powerful but more stable than it was and -FF will
-  be needed where -F in Zip 2.32 was enough.  One big change is -F and -FF
-  both now support split archives.
-- Console writing - Updates to how messages are written to the console have
-  been made including more consistent handling of line breaks.
-- Show Files options - Option -sf lists the files that would be operated
-  on.  This option can be used alone to list the files in an archive.
-  Also see options -su and -sU for showing Unicode paths.
-- UnZip Check - Now check that UnZip 6.00 or later is being used for
-  unzip if testing a Zip64 archive.  A new option -TT can be used to set
-  the unzip to use with the -T check.  Currently UnZip does not support
-  split archives so split archives can't be tested by UnZip.
-- Streaming - Directories are now handled better when streaming.
-- Case matching - Normally all matching against archive entries is case
-  sensitive, so *.BAR will not match or find foo.bar in an archive
-  when deleting, copying, or freshening entries (deleting and copying
-  only on VMS).  New option -ic (--ignore-case) enables case insensitive
-  matching.  Currently -ic is only implemented on WIN32 and VMS.
-
-- Delete date bug fixed - Bug when using -d to delete files while
-  using -t or -tt to select the files based on date is fixed
-- Large file encryption bug fixed - Fix for bug that very rarely
-  results in bad data being stored when deflating and encrypting
-  uncompressable data and resulting in CRC errors when extracting,
-  but the chance of error increases with file size (thanks to
-  WinZip for finding this bug).  See CHANGES for details.
-
-
-New things in Zip 3.0e
-
-- Bugs described in Debian patches 004 (unix configure script update) and
-  005 (large path bug) fixed
-- Various fixes
-- Add optional running stats and also end stats if not all files could
-  be read
-- Options -l and -ll now do quick binary check on first buffer and skip
-  formatting if first buffer has binary - still check at end to note
-  if formatting was done on file that was later determined to be binary,
-  but now potential file corruption is generally avoided
-- Main binary check now uses new algorithm that should also treat UTF-8 and
-  other similar encodings as text, allowing proper line end translation
-  for UTF-8 files
-- When output is not updatable by seeking back and Zip64 is enabled, output
-  is forced to Zip64 to avoid possible later need for Zip64 when not enabled
-- More work on splits, but still not usable
-- Fixes for djgpp
-- Add log file capability to save all errors and optionally messages
-- Add code to test for a Zip64 archive when compiled without Zip64 support
-- New VC6 projects for Win32 and WinDLL
-- Updates to extended help
-- Changes to force-zip64 option
-- ZE_BIG error now given also for files too big to read or write
-- Fix file delete bug
-- Update license
-- Update export documentation
-- Add VMS extended filename support
-- Add directory traversal improvements, some for Win32 ports and some for
-  all ports, that can result in a 10 times increase in speed in some cases
-
-
-New things in Zip 3.0d
-
-- Some large file crypt fixes
-- Some updates to support WiZ
-- On VMS, changed -V (/VMS) processing to truncate file at EOF, allowing
-  greater compatability with non-VMS systems.  New -VV (/VMS=ALL) option
-  saves all allocated blocks in a file.  (Previously, -V did neither.)
-- On VMS, pushed 2GB file size limit with -V out to 4GB
-- On VMS (recent, non-VAX), with SET PROCESS /PARSE = EXTEND,
-  command-line case is preserved.  This obviates quoting upper-case
-  options, like -V, when enabled
-- On VMS, fixed problems with mixed-case directory names.  Also changed
-  to keep ODS5 extended file name escape characters ("^") out of the
-  archived names in simple cases
-- Changes to the display dots
-- Option -W should now force wildcard matching to not cross directory
-  separators.  For example, a/b*r/d will match a/bar/d but not a/ba/r/d
-- Option -nw should turn off all wildcard matching so foo[bar] is matched
-  literally and [bar] is not considered a regular expression
-- Atheos port
-- Debugging of Unix and VMS large file ports.  Most features may work now
-  on these ports for large files.  Still need to fix 2 GB to 4 GB when not
-  compiled with large file support
-- On VMS, added an open callback function which (where supported) senses
-  the process RMS_DEFAULT values for file extend quantity (deq)
-  multi-block count (mbc), and multi-buffer count (mbf), and sets the
-  FAB/RAB parameters accordingly.  The default deq is now much larger
-  than before (16384 blocks, was none), and the default mbc is now 127
-  (up from 64), speeding creation of a large archive file.  The "-v"
-  option shows some of the activity.  On old VMS versions, RMS_DEFAULT
-  sensing (GETJPI) fails (silently, without "-v"), and no changes will
-  be made.  Even there, (DCL) SET RMS /EXTEND = <big> can help
-  performance.  RMS_DEFAULT values override built-in default values.
-
-
-New things in Zip 3.0c
-
-- Converted to using 64-bit file environment instead of transitional functions
-  like fseeko64 for ports that support it
-- Added "--" argument to read all following arguments as paths
-- Second help page added
-- Binary detection adjusted from 20% binary is binary to 2%
-- When -R and -i used together now -i has precedence over -R
-- Archive names with spaces can now be tested on MSDOS and Win32
-
-
-New things in Zip 3.0b
-
-- Fixed ifdefs so can test base code by compiling with NO_LARGE_FILE_SUPPORT, then
-  compiling with NO_ZIP64_SUPPORT to test 64-bit file calls (if port enables) but
-  otherwise use base code, and compiling normally to enable Zip64 code
-- Unix Zip64 fixes - should now be able to create and read large files
-- WinDLL changes to support Zip64.  Zip 3.0 dll named Zip32z64.dll
-- New VB example to show use of Zip32z64.dll
-- New options -sc (show final command line and exit) and -sd (show each
-  step zip is doing, a little different than verbose which is still there) added
-  to help debug but both or at least -sd might go away in the release
-- Some minor posted bugs fixed (see Changes)
-
-
-New things in Zip 3.0a
-
-- Initial Zip64 support allowing large files and large numbers of files
-- New command line processor
-- Other changes, see file Changes
-
-
-Note:  Zip 2.4 was never released.  That code was the start of the Zip 3.0
-effort above.
-
-
-New things in Zip 2.3
-
-- IBM OS/390 port (Unix like, but EBCDIC) by Paul von Behren
-- Apple Macintosh (MACOS) port by Dirk Haase
-- Theos port by Jean-Michel Dubois
-- Multibyte characterset support by Yoshioka Tsuneo
-- Support for ISO 8601 date format with -t and -tt options
-- Info-ZIP license
-
-
-New things in Zip 2.2
-
-- BEOS port by Chris Herborth
-- QDOS port by Jonathan Hudson
-- TANDEM port by Dave Smith
-- WINDLL port (16-bit Win 3.x and 32-bit WinNT/Win95) by Mike White
-- SYSV packages support by John Bush
-- zip -P SeCrEt encrypts entries in the zip file with password SeCrEt
-  (WARNING: THIS IS INSECURE, use at your own risk)
-- zip -R recurses into subdirectories of current dir like "PKZIP -rP"
-- zip -x@exclude.lst excludes files specified in the file exclude.lst
-- zip -i@include.lst includes files specified in the file include.lst
-- zip -@ only handles one filename per line, but supports whitespace in names
-- zip -t mmddyyyy, 4 digit year number for uniqueness of years beyond 2000
-- zip -tt mmddyyyy only includes files before a specified date

-[**] As of January 2000, US export regulations were amended to allow export
-     of free encryption source code from the US.  As of June 2002, these
-     regulations were further relaxed to allow export of encryption binaries
-     associated with free encryption source code.  The Zip 2.31, UnZip 5.52
-     and Wiz 5.02 archives now include full crypto source code.  As of the
-     Zip 2.31 release, all official binaries include encryption support; the

+Zip stores files in zip archives.  The default action is to add or replace\n\
+zipfile entries.\n\
+\n\
+Basic command line:\n\
+  zip options archive_name file file ...\n\
+\n\
+Some examples:\n\
+  Add file.txt to z.zip (create z if needed):      zip z file.txt\n\
+  Zip all files in current dir:                    zip z *\n\
+  Zip files in current dir and subdirs also:       zip -r z .\n\
+\n\
+Basic modes:\n\
+ External modes (selects files from file system):\n\
+        add      - add new files/update existing files in archive (default)\n\
+  -u    update   - add new files/update existing files only if later date\n\
+  -f    freshen  - update existing files only (no files added)\n\
+  -FS   filesync - update if date or size changed, delete if no OS match\n\
+ Internal modes (selects entries in archive):\n\
+  -d    delete   - delete files from archive (see below)\n\
+  -U    copy     - select files in archive to copy (use with --out)\n\
+\n\
+Basic options:\n\
+  -r        recurse into directories (see Recursion below)\n\
+  -m        after archive created, delete original files (move into archive)\n\
+  -j        junk directory names (store just file names)\n\
+  -q        quiet operation\n\
+  -v        verbose operation (just \"zip -v\" shows version information)\n\
+  -c        prompt for one-line comment for each entry\n\
+  -z        prompt for comment for archive (end with just \".\" line or EOF)\n\
+  -@        read names to zip from stdin (one path per line)\n\
+  -o        make zipfile as old as latest entry\n\
+\n\
+\n\
+Syntax:\n\
+  The full command line syntax is:\n\
+\n\
+    zip [-shortopts ...] [--longopt ...] [zipfile [path path ...]] [-xi list]\n\
+\n\
+  Any number of short option and long option arguments are allowed\n\
+  (within limits) as well as any number of path arguments for files\n\
+  to zip up.  If zipfile exists, the archive is read in.  If zipfile\n\
+  is \"-\", stream to stdout.  If any path is \"-\", zip stdin.\n\
+\n\
+Options and Values:\n\
+  For short options that take values, use -ovalue or -o value or -o=value\n\
+  For long option values, use either --longoption=value or --longoption value\n\
+  For example:\n\
+    zip -ds 10 --temp-dir=path zipfile path1 path2 --exclude pattern pattern\n\
+  Avoid -ovalue (no space between) to avoid confusion\n\
+  In particular, be aware of 2-character options.  For example:\n\
+    -d -s is (delete, split size) while -ds is (dot size)\n\
+  Usually better to break short options across multiple arguments by function\n\
+    zip -r -dbdcds 10m -lilalf logfile archive input_directory -ll\n\
+\n\
+  All args after just \"--\" arg are read verbatim as paths and not options.\n\
+    zip zipfile path path ... -- verbatimpath verbatimpath ...\n\
+  Use -nw to also disable wildcards, so paths are read literally:\n\
+    zip zipfile -nw -- \"-leadingdashpath\" \"a[path].c\" \"path*withwildcard\"\n\
+  You may still have to escape or quote arguments to avoid shell expansion\n\
+\n\
+Wildcards:\n\
+  Internally zip supports the following wildcards:\n\
+    ?       (or %% or #, depending on OS) matches any single character\n\
+    *       matches any number of characters, including zero\n\
+    [list]  matches char in list (regex), can do range [ac-f], all but [!bf]\n\
+  If port supports [], must escape [ as [[] or use -nw to turn off wildcards\n\
+  For shells that expand wildcards, escape (\\* or \"*\") so zip can recurse\n\
+    zip zipfile -r . -i \"*.h\"\n\
+\n\
+  Normally * crosses dir bounds in path, e.g. 'a*b' can match 'ac/db'.  If\n\
+   -ws option used, * does not cross dir bounds but ** does\n\
+\n\
+  For DOS and Windows, [list] is now disabled unless the new option\n\
+  -RE       enable [list] (regular expression) matching\n\
+  is used to avoid problems with file paths containing \"[\" and \"]\":\n\
+    zip files_ending_with_number -RE foo[0-9].c\n\
+\n\
+Include and Exclude:\n\
+  -i pattern pattern ...   include files that match a pattern\n\
+  -x pattern pattern ...   exclude files that match a pattern\n\
+  Patterns are paths with optional wildcards and match paths as stored in\n\
+  archive.  Exclude and include lists end at next option, @, or end of line.\n\
+    zip -x pattern pattern @ zipfile path path ...\n\
+\n\
+Case matching:\n\
+  On most OS the case of patterns must match the case in the archive, unless\n\
+  the -ic option is used.\n\
+  -ic       ignore case of archive entries\n\
+  This option not available on case-sensitive file systems.  On others, case\n\
+  ignored when matching files on file system but matching against archive\n\
+  entries remains case sensitive for modes -f (freshen), -U (archive copy),\n\
+  and -d (delete) because archive paths are always case sensitive.  With\n\
+  -ic, all matching ignores case, but it's then possible multiple archive\n\
+  entries that differ only in case will match.\n\
+\n\
+End Of Line Translation (text files only):\n\
+  -l        change CR or LF (depending on OS) line end to CR LF (Unix->Win)\n\
+  -ll       change CR LF to CR or LF (depending on OS) line end (Win->Unix)\n\
+  If first buffer read from file contains binary the translation is skipped\n\
+\n\
+Recursion:\n\
+  -r        recurse paths, include files in subdirs:  zip -r a path path ...\n\
+  -R        recurse current dir and match patterns:   zip -R a ptn ptn ...\n\
+  Use -i and -x with either to include or exclude paths\n\
+  Path root in archive starts at current dir, so if /a/b/c/file and\n\
+   current dir is /a/b, 'zip -r archive .' puts c/file in archive\n\
+\n\
+Date filtering:\n\
+  -t date   exclude before (include files modified on this date and later)\n\
+  -tt date  include before (include files modified before date)\n\
+  Can use both at same time to set a date range\n\
+  Dates are mmddyyyy or yyyy-mm-dd\n\
+\n\
+Deletion, File Sync:\n\
+  -d        delete files\n\
+  Delete archive entries matching internal archive paths in list\n\
+    zip archive -d pattern pattern ...\n\
+  Can use -t and -tt to select files in archive, but NOT -x or -i, so\n\
+    zip archive -d \"*\" -t 2005-12-27\n\
+  deletes all files from archive.zip with date of 27 Dec 2005 and later\n\
+  Note the * (escape as \"*\" on Unix) to select all files in archive\n\
+\n\
+  -FS       file sync\n\
+  Similar to update, but files updated if date or size of entry does not\n\
+  match file on OS.  Also deletes entry from archive if no matching file\n\
+  on OS.\n\
+    zip archive_to_update -FS -r dir_used_before\n\
+  Result generally same as creating new archive, but unchanged entries\n\
+  are copied instead of being read and compressed so can be faster.\n\
+      WARNING:  -FS deletes entries so make backup copy of archive first\n\
+\n\
+Compression:\n\
+  -0        store files (no compression)\n\
+  -1 to -9  compress fastest to compress best (default is 6)\n\
+  -Z cm     set compression method to cm:\n\
+              store   - store without compression, same as option -0\n\
+              deflate - original zip deflate, same as -1 to -9 (default)\n\
+              bzip2 - use bzip2 compression (need modern unzip)\n\
+\n\
+Encryption:\n\
+  -e        use standard (weak) PKZip 2.0 encryption, prompt for password\n\
+  -P pswd   use standard encryption, password is pswd\n\

+  -sp       pause after each split closed to allow changing disks\n\
+      WARNING:  Archives created with -sp use data descriptors and should\n\
+                work with most unzips but may not work with some\n\
+  -sb       ring bell when pause\n\
+  -sv       be verbose about creating splits\n\
+      Split archives CANNOT be updated, but see --out and Copy Mode below\n\
+\n\
+Using --out (output to new archive):\n\
+  --out oa  output to new archive oa\n\
+  Instead of updating input archive, create new output archive oa.\n\
+  Result is same as without --out but in new archive.  Input archive\n\
+  unchanged.\n\
+      WARNING:  --out ALWAYS overwrites any existing output file\n\
+  For example, to create new_archive like old_archive but add newfile1\n\
+  and newfile2:\n\
+    zip old_archive newfile1 newfile2 --out new_archive\n\
+  Cannot update split archive, so use --out to out new archive:\n\
+    zip in_split_archive newfile1 newfile2 --out out_split_archive\n\
+  If input is split, output will default to same split size\n\
+  Use -s=0 or -s- to turn off splitting to convert split to single file:\n\
+    zip in_split_archive -s 0 --out out_single_file_archive\n\
+      WARNING:  If overwriting old split archive but need less splits,\n\
+                old splits not overwritten are not needed but remain\n\
+\n\
+Copy Mode (copying from archive to archive):\n\
+  -U        (also --copy) select entries in archive to copy (reverse delete)\n\

+  To copy only files matching *.c into new archive, excluding foo.c:\n\

+  zip - -R \"*.c\" | prog2   zip *.c files in current dir and stream to prog2 \n\
+  prog1 | zip | prog2      zip in pipe with no in or out acts like zip - -\n\
+  If Zip is Zip64 enabled, streaming stdin creates Zip64 archives by default\n\
+   that need PKZip 4.5 unzipper like UnZip 6.0\n\
+  WARNING:  Some archives created with streaming use data descriptors and\n\
+            should work with most unzips but may not work with some\n\
+  Can use -fz- to turn off Zip64 if input not large (< 4 GB):\n\
+    prog_with_small_output | zip archive -fz-\n\
+\n\
+  Zip now can read Unix FIFO (named pipes).  Off by default to prevent zip\n\
+  from stopping unexpectedly on unfed pipe, use -FI to enable:\n\
+    zip -FI archive fifo\n\
+\n\
+Dots, counts:\n\
+  -db       display running count of bytes processed and bytes to go\n\
+              (uncompressed size, except delete and copy show stored size)\n\
+  -dc       display running count of entries done and entries to go\n\
+  -dd       display dots every 10 MB (or dot size) while processing files\n\
+  -dg       display dots globally for archive instead of for each file\n\
+    zip -qdgds 10m   will turn off most output except dots every 10 MB\n\
+  -ds siz   each dot is siz processed where siz is nm as splits (0 no dots)\n\
+  -du       display original uncompressed size for each entry as added\n\
+  -dv       display volume (disk) number in format in_disk>out_disk\n\
+  Dot size is approximate, especially for dot sizes less than 1 MB\n\
+  Dot options don't apply to Scanning files dots (dot/2sec) (-q turns off)\n\
+\n\
+Logging:\n\
+  -lf path  open file at path as logfile (overwrite existing file)\n\
+  -la       append to existing logfile\n\
+  -li       include info messages (default just warnings and errors)\n\
+\n\
+Testing archives:\n\
+  -T        test completed temp archive with unzip before updating archive\n\
+  -TT cmd   use command cmd instead of 'unzip -tqq' to test archive\n\
+             On Unix, to use unzip in current directory, could use:\n\
+               zip archive file1 file2 -T -TT \"./unzip -tqq\"\n\
+             In cmd, {} replaced by temp archive path, else temp appended.\n\
+             The return code is checked for success (0 on Unix)\n\
+\n\
+Fixing archives:\n\
+  -F        attempt to fix a mostly intact archive (try this first)\n\
+  -FF       try to salvage what can (may get more but less reliable)\n\
+  Fix options copy entries from potentially bad archive to new archive.\n\
+  -F tries to read archive normally and copy only intact entries, while\n\
+  -FF tries to salvage what can and may result in incomplete entries.\n\
+  Must use --out option to specify output archive:\n\
+    zip -F bad.zip --out fixed.zip\n\
+  Use -v (verbose) with -FF to see details:\n\
+    zip reallybad.zip -FF -v --out fixed.zip\n\
+  Currently neither option fixes bad entries, as from text mode ftp get.\n\
+\n\
+Difference mode:\n\
+  -DF       (also --dif) only include files that have changed or are\n\
+             new as compared to the input archive\n\
+  Difference mode can be used to create incremental backups.  For example:\n\
+    zip --dif full_backup.zip -r somedir --out diff.zip\n\
+  will store all new files, as well as any files in full_backup.zip where\n\
+  either file time or size have changed from that in full_backup.zip,\n\
+  in new diff.zip.  Output archive not excluded automatically if exists,\n\
+  so either use -x to exclude it or put outside what is being zipped.\n\
+\n\
+DOS Archive bit (Windows only):\n\
+  -AS       include only files with the DOS Archive bit set\n\
+  -AC       after archive created, clear archive bit of included files\n\
+      WARNING: Once the archive bits are cleared they are cleared\n\
+               Use -T to test the archive before the bits are cleared\n\
+               Can also use -sf to save file list before zipping files\n\
+\n\
+Show files:\n\
+  -sf       show files to operate on and exit (-sf- logfile only)\n\
+  -su       as -sf but show escaped UTF-8 Unicode names also if exist\n\
+  -sU       as -sf but show escaped UTF-8 Unicode names instead\n\
+  Any character not in the current locale is escaped as #Uxxxx, where x\n\
+  is hex digit, if 16-bit code is sufficient, or #Lxxxxxx if 24-bits\n\
+  are needed.  If add -UN=e, Zip escapes all non-ASCII characters.\n\
+\n\
+Unicode:\n\
+  If compiled with Unicode support, Zip stores UTF-8 path of entries.\n\
+  This is backward compatible.  Unicode paths allow better conversion\n\
+  of entry names between different character sets.\n\
+\n\
+  New Unicode extra field includes checksum to verify Unicode path\n\
+  goes with standard path for that entry (as utilities like ZipNote\n\
+  can rename entries).  If these do not match, use below options to\n\
+  set what Zip does:\n\
+      -UN=Quit     - if mismatch, exit with error\n\
+      -UN=Warn     - if mismatch, warn, ignore UTF-8 (default)\n\
+      -UN=Ignore   - if mismatch, quietly ignore UTF-8\n\
+      -UN=No       - ignore any UTF-8 paths, use standard paths for all\n\
+  An exception to -UN=N are entries with new UTF-8 bit set (instead\n\
+  of using extra fields).  These are always handled as Unicode.\n\
+\n\
+  Normally Zip escapes all chars outside current char set, but leaves\n\
+  as is supported chars, which may not be OK in path names.  -UN=Escape\n\
+  escapes any character not ASCII:\n\
+    zip -sU -UN=e archive\n\
+  Can use either normal path or escaped Unicode path on command line\n\
+  to match files in archive.\n\
+\n\
+  Zip now stores UTF-8 in entry path and comment fields on systems\n\
+  where UTF-8 char set is default, such as most modern Unix, and\n\
+  and on other systems in new extra fields with escaped versions in\n\
+  entry path and comment fields for backward compatibility.\n\
+  Option -UN=UTF8 will force storing UTF-8 in entry path and comment\n\
+  fields:\n\
+      -UN=UTF8     - store UTF-8 in entry path and comment fields\n\
+  This option can be useful for multi-byte char sets on Windows where\n\
+  escaped paths and comments can be too long to be valid as the UTF-8\n\
+  versions tend to be shorter.\n\
+\n\
+  Only UTF-8 comments on UTF-8 native systems supported.  UTF-8 comments\n\
+  for other systems planned in next release.\n\
+\n\
+Self extractor:\n\
+  -A        Adjust offsets - a self extractor is created by prepending\n\
+             the extractor executable to archive, but internal offsets\n\
+             are then off.  Use -A to fix offsets.\n\
+  -J        Junk sfx - removes prepended extractor executable from\n\
+             self extractor, leaving a plain zip archive.\n\
+\n\
+More option highlights (see manual for additional options and details):\n\
+  -b dir    when creating or updating archive, create the temp archive in\n\
+             dir, which allows using seekable temp file when writing to a\n\
+             write once CD, such archives compatible with more unzips\n\
+             (could require additional file copy if on another device)\n\
+  -MM       input patterns must match at least one file and matched files\n\
+             must be readable or exit with OPEN error and abort archive\n\
+             (without -MM, both are warnings only, and if unreadable files\n\
+             are skipped OPEN error (18) returned after archive created)\n\
+  -nw       no wildcards (wildcards are like any other character)\n\
+  -sc       show command line arguments as processed and exit\n\
+  -sd       show debugging as Zip does each step\n\
+  -so       show all available options on this system\n\
+  -X        default=strip old extra fields, -X- keep old, -X strip most\n\
+  -ws       wildcards don't span directory boundaries in paths\n\
