And now I can't figure out what I need to enable to have "rewrite" work.
Good job!

The names match the internal module names, which is what I care about.
Figuring out if I need USE="zlib" or USE="compress" or even a combo is a
lot more effort and frustrating than having to enable the useflag that
has the name of the module.

It might not be 'pure' or very aesthetical, but we try to get stuff done
here.
