If it's package data inside the package, it should all end up in the 
right place for importlib.resources to find.

Python build tools don't provide a mechanism to install things like 
manpages into the right place (because python packaging isn't aimed at a 
complete system, but a Python environment). So the packager has to move 
things around, themselves.

>/usr/share/locale.

I don't know the correct pattern for this offhand, but I'd imagine that 
you can try both a path located via improtlib.resources, and the default 
localedir, when configuring your translations.

Pip is not used. We use "build", another PEP 517 implementation, to 
build a wheel, that we then install the contents of.
