{- | Merge a package from hackage to an ebuild.
Merging a library
=================
Compile time:
ghc
cabal
build tools
deps (haskell dependencies)
extra-libs (c-libs)
pkg-config (c-libs)
Run time:
ghc
deps (haskell dependencies)
extra-libs (c-libs)
pkg-config (c-libs)
RDEPEND="ghc ${DEPS} ${EXTRALIBS}"
DEPEND="${RDEPEND} cabal ${BUILDTOOLS}"
Merging an executable
=====================
Packages with both executable and library must be treated as libraries, as it will impose a stricter DEPEND.
Compile time:
ghc
cabal
build tools
deps (haskell dependencies)
extra-libs (c-libs)
pkg-config (c-libs)
Run time:
extra-libs (c-libs)
pkg-config (c-libs)
RDEPEND="${EXTRALIBS}"
DEPEND="${RDEPEND} ghc cabal ${DEPS} ${BUILDTOOLS}"
