+New in v0.7.3 (2002/04/29)
+--------------------------
+
+Fixed broken remote operation in v0.7.2 by applying (a variant of)
+Daniel Robbins' patch.  Also fixed associated bug in test set.
+
+Fixed bug recognizing --[include|exclude]-filelist-stdin options, and
+IndexError bug reading some filelists.
+
+--force is no longer necessary if the target directory is empty.
+
+--include/--exclude/etc now work for restoring as they do for backing up.
+
+Raised verbosity level for traceback output - if long log error
+messages are annoying you, set verbosity to 2.  Will come up with a
+better logging system later.
+
+May have fixed a problem encountered by Matthew Farrellee and Kevin
+Spicer wherein the _session_info_list information was stored on the
+wrong computer.  This could cause rdiff-backup to fail when running
+after another backup that failed for a different reason.  May backport
+this fix to 0.6.0 later.
+
+May have fixed a problem also noticed by Matthew Farrellee which can
+cause rdiff-backup to exit when a directory changes into into a
+non-directory file while rdiff-backup is processing the directory.
+(May also apply to 0.6.0).
+
+Fixed a bug noticed by Jamie Heilman where restoring could fail if a
+recent rdiff-backup process which produced the backup set was aborted
+while processing a new directory.  (May also apply to 0.6.0)
+
+

-Accept a list of files??

 Security audit
 
 Don't produce stack trace which looks like crash/include file name in

+Add to above Dean Gaudet's suggestion: make errors look prettier (like tar).

+Add new restore option - bring directory to state it was in, say, 5
+days ago, etc.

 Michael S. Muegel suggestion: "--char-translate source-char
 replacement-string" for use between windows/unix conversions, e.g. ':'
 to _colon_.  Also distinguish new vs changed update in lvl 5 logging.
