Just in case this isn't clear yet - Cabal is not meant to be a replacement
for native Debian packages, it is supposed to let the Debian folks package
Haskell stuff more easily. We didn't want to duplicate everything that a
good OS packaging system does in Cabal, that's just a waste of time and
likely to conflict with what the OS packager is already doing.
Sounds like the Debian folks could use some help with automatically
packaging Cabal packages, though.
