/* A set of aliases to be used in generated expressions.
In case of ambiguity, this will pick a sensible default.
This was initially based on cabal2nix's mapping.
It'd be nice to generate this mapping, based on a set of derivations.
It can not be fully automated, so it should be a expression or tool
that makes suggestions about which pkg-config module names can be added.
