+Suggestions for improving GNU tar.
 
-It would be useful to be able to use '--remove-files' with '--diff',
-to remove all files that compare successfully, when verifying a backup.
+* Incorporate fixes from major distributions, e.g., Debian GNU/Linux.
+
+* Fix tar so that it can read and write POSIX.1-1990 tar archives.
+
+* Add support for POSIX 1003.1-2001 tar archives
+  (along with technical corrections to the standard since 2001).
+
+* Add support for a 'pax' command that conforms to POSIX 1003.1-2001.
+  This would unify paxutils with tar.
+
+* Remove command-line incompatibilities between GNU tar and UNIX tar
+  as specified by UNIX98.  The main problems are:
+
+     l   GNU tar doesn't cross filesystem boundaries.
+	 UNIX98 tar warns if all links cannot be resolved.
+	   (GNU tar has no similar option.)
+
+     o   GNU tar says output old format.
+	 UNIX98 tar says don't chown files after extracting
+	   (GNU tar uses "--no-same-owner" for this).
+
+  Many people rely on GNU tar's "l" and "o" so we can't abruptly change
+  GNU tar to be compatible with UNIX98 tar.
+
+  However, "o" is relatively easy: we can extend GNU tar so that "o" is
+  a synonym for --no-same-owner when extracting, keeping "o"'s current
+  semantics when creating.  This is a bit of a hack, but it shouldn't
+  break things.
+
+  "l" will be harder, since it's a clear incompatibility.  Perhaps we
+  could announce a phase-in period where "l" changes in semantics.
+  However, the first step should be to support the UNIX98 semantics,
+  using a long option, without changing the meaning of "l" for now.  That
+  will give people a migration strategy.
+
+* Interoperate better with Joerg Schilling's star implementation.
+
+* Add an option to remove files that compare successfully.
