# FIXME: Needs tidying into separate functions.
# FIXME: Some of this is duplicated from release-wrangler.
# This should go in a common library when the dust has settled.
# FIXME: Some way of updating Bugzilla when we mention a bug,
# and including the revision number, would be really useful.
# FIXME: This should co-operate with patch-wrangler in that
# p-w should find out the name of a patch's submitter from bugzilla
# and store it in a dotfile, and then we can use it here.
# Also, it should find out and store the bug number, so we can
# write it as "(Bug #nnn)", which will make the previous paragraph's
# idea even more useful.
