+=================

+NAME
+----
+git-merge-base - Find as good common ancestors as possible for a merge
+
+
+SYNOPSIS
+--------
+'git-merge-base' [--all] <commit> <commit>
+
+DESCRIPTION
+-----------
+
+"git-merge-base" finds as good a common ancestor as possible between
+the two commits. That is, given two commits A and B 'git-merge-base A
+B' will output a commit which is reachable from both A and B through
+the parent relationship.
+
+Given a selection of equally good common ancestors it should not be
+relied on to decide in any particular way.
+
+The "git-merge-base" algorithm is still in flux - use the source...
+
+OPTIONS
+-------
+--all::
+ Output all common ancestors for the two commits instead of
+ just one.
