git archive

To extract the current directory into a tar with a prefix:

git archive $tag –prefix $prefix/ . | gzip > $packagename.tar.gz

I think $prefix and $packagename will often be identical. $prefix will often include at leart part of $tag.

Examples:

git archive agestat-2022.09.02 --prefix agestat-2022.09.02/ . | gzip > agestat-2022.09.02.tar.gz

git archive release-2.9 --prefix theprogram-2.9/ . | gzip > theprogram-2.9.tar.gz
