30# 32# only used for packages that _must_ not pull the dependency
31# Cabal libraries should usually be SLOTted with "${PV}". 33# on cabal, but still use this eclass (e.g. haskell-updater).
32# 34# test-suite -- add support for cabal test-suites (introduced in Cabal-1.8)
33# Many Cabal packages require S to be manually set.

35# Conforming Cabal packages don't require any function definitions
36# in the ebuild.
