 One option is to generate a `.tar` or a `.tar.[gz|bz2|xz]` and calculate
 the checksum of that. There are other options for sure.

 you want.

 I meant something that would easily be accessible in Tcl, so that I could
 specify something like
 {{{
     git.branch ...sha...
     version "3.14-beta-${git.commitdate}-${git.shortsha}"
 }}}
 I would need to learn how to interface git and Tcl first to implement
 that.
