9     # This eclass is for packages that make use of the
10     # Haskell Common Architecture for Building Applications
11     # and Libraries (cabal).
12     #
13     # 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     # alex -- lexer/scanner generator
22     # happy -- parser generator
23     # c2hs -- C interface generator
24     # cpphs -- C preprocessor clone written in Haskell
25     # profile -- if package supports to build profiling-enabled libraries
26     # bootstrap -- only used for the cabal package itself
27 dcoutts 1.3 # bin -- the package installs binaries
28     # lib -- the package installs libraries
29 kosmikus 1.1 #
30     # Dependencies on other cabal packages have to be specified
31     # correctly.
32     #
33     # Cabal libraries should usually be SLOTted with "${PV}".
34     #
35     # Many Cabal packages require S to be manually set.
36     #
37     # Conforming Cabal packages don't require any function definitions
38     # in the ebuild.
39 kosmikus 1.8 #
40     # Special flags to Cabal Configure can now be set by using
41     # CABAL_CONFIGURE_FLAGS
