git migration scheduled for 11 March 2014

[Mark Côté]

The mirroring script is now running every 5 minutes on the new
migration_test Bugzilla branch.

See
http://git.mozilla.org/?p=bugzilla/bugzilla.git;a=shortlog;h=refs/heads/migration_test
for the log of changes to this branch in git.  Within 5 minutes, any
changes should be visible on bzr at
http://bzr.mozilla.org/bugzilla/migration_test/changes.  Note that each
bzr commit will also have a change to the .gitrev file, which keeps
track of which git commits have already been mirrored over.

Anyone with commit access to Bugzilla on bzr.mozilla.org should have
commit access to the Bugzilla git repo; I invite you to make some
changes to the migration_test branch and ensure that they appear
correctly in bzr.

My last task is updating the wiki pages concerning the submission of
patches to Bugzilla.  The migration date of 11 March 2014 is still in place.
