That is, given two commits A and B 'git-merge-base A 18B' will output a commit which is reachable from both A and B through 19the parent relationship. 20 21Given a selection of equally good common ancestors it should not be 22relied on to decide in any particular way. 23 24The "git-merge-base" algorithm is still in flux - use the source... 25 26OPTIONS 27------- 28--all:: 29 Output all common ancestors for the two commits instead of 30 just one. 31 32Author 33------ 34Written by Linus Torvalds <torvalds@osdl.org> 35 36Documentation 37-------------- 38Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>. 39 40GIT 41--- 42Part of the linkgit:git[7] suite
