+Synopsis: %(prog)s [-h|-b|-g|-r|-a|-d] [ picklefile ] dbfile
+
+Read the given picklefile as a series of key/value pairs and write to a new
+database.  If the database already exists, any contents are deleted.  The
+optional flags indicate the type of the output database:
+
+    -a - open using dbm (open any supported format)
+    -b - open as bsddb btree file
+    -d - open as dbm.ndbm file
+    -g - open as dbm.gnu file
+    -h - open as bsddb hash file
+    -r - open as bsddb recno file
+
+The default is hash.  If a pickle file is named it is opened for read
+access.  If no pickle file is named, the pickle input is read from standard
+input.
+
+Note that recno databases can only contain integer keys, so you can't dump a
+hash or btree database using db2pickle.py and reconstitute it to a recno
+database with %(prog)s unless your keys are integers.
