Courtès: What's in a package

Sometimes it's just picking up an older tarball and building it, other times it's creating a small branch in git with a few commits.

And it's definitely possible to make the "light fork" parallel-installable with the main, upstream version, so that Linux distros can install both, see for example:
https://developer.gnome.org/documentation/guidelines/main...
(this is used for instance for the different major versions of GTK, they can co-exist on the same prefix).
