We're targeting Python 2.7.
Trouble is that pkgutil.walk_packages needs a path to search from.
Distribution.location is always your site-packages directory once a
Distribution is installed, so walking that just gives ALL installed
packages. If your Distribution contains some sort of main package that
contains everything in it, you can use that package's .__path__, but
then you'd need to discover what that package is.
Distributions could also contain more than one package next to each
other, and top-level modules. (The __path__ of a top-level module is
also simply the site-packages directory.)
There is a metadata file top_level.txt which one could use to get the
names of top-level packages/modules in the Distribution. This can
however contain a namespace package too - and you don't want all the
packages inside the namespace package - just the bits inside the chosen
Distribution...
