Log Message:
Update to 0.33.  Tested in NetBSD-current and Mac OS X.  Changes:

        The internal data format has changed with this release;
        migration is straight-forward.  To upgrade your databases,
	you must run:
               $ mtn -d mydb.mtn db migrate
        All of these operations are completely lossless, and 0.33
        remains compatible with earlier versions with regards to
        netsync.

        Changes

        - "mtn ls unknown" no longer recurses into unknown directories.

        - update will fail rather than clobbering unversioned files
          that exist in the workspace.

        - update will detect directories with unversioned files before
          attempting to drop them and will refuse to run rather than
          corrupting the workspace. such unversioned files must be
          removed manually.

        - the character set and line separator conversion hooks
          (get_system_linesep, get_charset_conv and get_linesep_conv)
          have been removed. Similar functionality (probably based on
          file type attributes) is planned and will be added in a future
          release.

	- update will switch to the branch of a given revision if it
	  differs from the current workspace branch.

	- add will now accept combinations of --unknown, --recursive and
	  --no-respect-ignore.

	- import now imports unknown directory trees properly.

	- use SQLite 3.3.12.

	- schema migrator rebuilt and will now properly detect and report
	  if the database used is created by a newer monotone than the one
	  currently used.

	- removed the man page mtn.1, as it hadn't been updated for a long
	  time.

	New features

	- "mtn merge_into_workspace" (still to be documented)

	- "mtn log" will now print an ASCII revision graph alongside the
	  usual log text.

	Speed improvements

	- "mtn annotate file" should run even faster now. it exploits
	  the fact that we store deltas of rosters. by peeking at
	  these deltas, it can avoid reconstruction of whole rosters
	  in many cases.

	Other

	- contrib/monotone-mirror.sh and
	  contrib/monotone-mirror-postaction-update.sh, two scripts
	  to mirror and update directories automatically.

	- contrib/monotone-run-script-post-netsync.lua, to automatically
	  update a directory as soon as new revisions or certs arrive for
	  a given branch.

	- contrib/monotone.bash_completion had some improvemens.

	- contrib/monotone.el had some improvements.

	Internal

	- Internally, the concept of "projects" has been introduced.  It
	  currently doesn't mean anything, but will be used later, with
	  policy branches and similar.
