An important part of a *binary-only* environment is to support something similar
to the existing options framework, but produce different combinations of pkgs.
There is an undefined amount of work required to accomplish this, and also a set
of standards and naming conventions to be applied for the output of these pkgs.
This project should also save on having to rebuild "base" components of software
to support different options: see amanda-base for an example.
OpenBSD supports this now and should be leveraged heavily for borrowing.
