11     # @BLURB: for packages that make use of the Haskell Common Architecture for Building Applications and Libraries (cabal)
12     # @DESCRIPTION:
13 kosmikus 1.1 # Basic instructions:
14     #
15     # Before inheriting the eclass, set CABAL_FEATURES to
16     # reflect the tools and features that the package makes
17     # use of.
18     #
19     # Currently supported features:
20     # haddock -- for documentation generation
21 kolmodin 1.21 # hscolour -- generation of colourised sources
22 slyfox 1.35 # hoogle -- generation of documentation search index
23 kosmikus 1.1 # alex -- lexer/scanner generator
24     # happy -- parser generator
25     # c2hs -- C interface generator
26     # cpphs -- C preprocessor clone written in Haskell
27     # profile -- if package supports to build profiling-enabled libraries
28     # bootstrap -- only used for the cabal package itself
29 dcoutts 1.3 # bin -- the package installs binaries
30     # lib -- the package installs libraries
31 kolmodin 1.16 # nocabaldep -- don't add dependency on cabal.
32 slyfox 1.23 # only used for packages that _must_ not pull the dependency
33     # on cabal, but still use this eclass (e.g. haskell-updater).
34 slyfox 1.32 # test-suite -- add support for cabal test-suites (introduced in Cabal-1.8)
