+In particular, check the ChangeLog entries (eg in case too many

+bzrmerge tries to fix up the dates to today's date, but it only does
+this where there are conflicts.  If you used the changelog_merge plugin,
+there won't be any conflicts, and (at time of writing) you will need
+to adjust dates by hand.  In any case, if someone made multiple
+ChangeLog entries on different days in the branch, you may wish to
+collapse them all to a single entry for that author in the trunk
+(because in the trunk they all appear under the same date).
+Obviously, if there are multiple changes to the same file by different
