From a8783eeb7988a20664dade2379d380ee1a199a10 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 18 Sep 2005 11:18:30 -0700 Subject: [PATCH] [PATCH] Add "--git-dir" flag to git-rev-parse Especially when you're deep inside the git repository, it's not all that trivial for scripts to figure out where GIT_DIR is if it isn't set. So add a flag to git-rev-parse to show where it is, since it will have figured it out anyway.
