Here's another question: Where would you get the git commit number and
date from, if the source tree from which you build is not under git
control?  For instance if you use the release source tar archive, or if
you use a vendor's source rpm.  Sorry if that's a dumb question.

As in OpenSSL, no character is 0, 'a' is 1, 'b' is 2, etc.  See
<openssl/opensslv.h>.  Samba could use the same version number layout.
The data is completely available in include/version.h, afaics.

Will do, thanks.

Ok, thank you,
