If the tar-file download doesn't include the revision in its filename
and the directory it unpacks then I'd either post-process it to do that
or stop using the web download and do a proper ‘release’ target in the
software's makefile. Then when you want a release to ship you
make REV=12345678ab release
and it creates a ‘wmt-12345678ab.tar.lzip’ or similar which is a
check-out of that revision from the public repo into directory
‘wmt-12345678ab’, all tar'd up.
You can ship those tar files about, unpack them, and then alter a ‘wmt’
symbolic link to move between which version will be used, allowing for
easy downgrade on a machine with no Internet.
Code can inspect the ‘real’ path to its location to determine its
version for logging, etc.
