you use:  git describe --dirty

That's all that's really needed.  The version will be like:
 v0.25pre-1397-gb584b68

the first part (to the -) corresponds to what the last tag was..  The second
is the number of commits after that tag, and the third (which IS necessary)
-- less the "g" -- is the beginning of the SHA1 of the last commit.  There
can also be a -dirty at the end if you have custom stuff in there (not
committed).

I don't know why you'd want to decompose the git describe information in the
way the previous poster did.  For support, the developers will be wanting
the version number as I outlined, and the branch you are on (from git
branch, it's the one with the * beside).  This data is also compiled into
the binaries, and is available from "mythfrontend --version" or "mythbackend
--version".
