+Welcome to the "PC" subdirectory of the Python distribution
+***********************************************************
+
+This "PC" subdirectory contains complete project files to make
+several older PC ports of Python, as well as all the PC-specific
+Python source files.  It should be located in the root of the
+Python distribution, and there should be directories "Modules",
+"Objects", "Python", etc. in the parent directory of this "PC"
+subdirectory.  Be sure to read the documentation in the Python
+distribution.
+
+Python requires library files such as string.py to be available in
+one or more library directories.  The search path of libraries is
+set up when Python starts.  To see the current Python library search
+path, start Python and enter "import sys" and "print sys.path".
+
+All PC ports use this scheme to try to set up a module search path:
+
+  1) The script location; the current directory without script.
+  2) The PYTHONPATH variable, if set.
+  3) For Win32 platforms (NT/95), paths specified in the Registry.
+  4) Default directories lib, lib/win, lib/test, lib/tkinter;
+     these are searched relative to the environment variable
+     PYTHONHOME, if set, or relative to the executable and its
+     ancestors, if a landmark file (Lib/string.py) is found ,
+     or the current directory (not useful).
+  5) The directory containing the executable.
+
+The best installation strategy is to put the Python executable (and
+DLL, for Win32 platforms) in some convenient directory such as
+C:/python, and copy all library files and subdirectories (using XCOPY)
+to C:/python/lib.  Then you don't need to set PYTHONPATH.  Otherwise,
+set the environment variable PYTHONPATH to your Python search path.
+For example,
+   set PYTHONPATH=.;d:\python\lib;d:\python\lib\win;d:\python\lib\dos-8x3
+
+There are several add-in modules to build Python programs which use
+the native Windows operating environment.  The ports here just make
+"QuickWin" and DOS Python versions which support a character-mode
+(console) environment.  Look in www.python.org for Tkinter, PythonWin,
+WPY and wxPython.
+
+To make a Python port, start the Integrated Development Environment
+(IDE) of your compiler, and read in the native "project file"
+(or makefile) provided.  This will enable you to change any source
+files or build settings so you can make custom builds.
+
+pyconfig.h    An important configuration file specific to PC's.
+
+config.c    The list of C modules to include in the Python PC
+            version.  Manually edit this file to add or
+            remove Python modules.
+
+testpy.py   A Python test program.  Run this to test your
+            Python port.  It should produce copious output,
+	    ending in a report on how many tests were OK, how many
+	    failed, and how many were skipped.  Don't worry about
+	    skipped tests (these test unavailable optional features).
+
+
+Additional files and subdirectories for 32-bit Windows
+======================================================
+
+python_nt.rc   Resource compiler input for python15.dll.
+
+dl_nt.c
+               Additional sources used for 32-bit Windows features.
+
+getpathp.c     Default sys.path calculations (for all PC platforms).
+
+dllbase_nt.txt A (manually maintained) list of base addresses for
+               various DLLs, to avoid run-time relocation.
+
+
+Note for Windows 3.x and DOS users
+==================================
+
+Neither Windows 3.x nor DOS is supported any more.  The last Python
+version that supported these was Python 1.5.2; the support files were
+present in Python 2.0 but weren't updated, and it is not our intention
+to support these platforms for Python 2.x.
