"git find" command

gistfile1.cfg

[alias]
        ; "git find" should work exactly like your system find (BSD or GNU), except for
        ; two things: one, it will always ignore the current git directory; and two, if
        ; you don't supply any root paths to search, it defaults to searching from your
        ; git project toplevel.
