+#
+# This Makefile fragment handles Haskell Cabal packages.
+# See: http://www.haskell.org/cabal/
+#
+# Note to users:
+#
+#   * Users choose one favourite Haskell compiler. Though the only
+#     compiler currently supported is GHC.
+#
+#   * You can't install a cabal package for more than one compilers
+#     simultaneously. In the future, this limitation can possibly be
+#     eliminated using the method used by
+#     "../../lang/python/pyversion.mk".
+#
+# Note to package developers:
+#
+#   * This file must be included *before* "../../mk/bsd.pkg.mk", or
+#     you'll get target-redefinition errors.
+#
+#   * PKGNAME will automatically be "hs-${DISTNAME}" unless you
+#     explicitly declare it.
+# 
+#   * If your package is on the HackageDB, MASTER_SITES and HOMEPAGE
+#     can be omitted.
+#
+#   * Package configuration, building, installation, registration and
+#     unregistration are fully automated. You usually don't need to do
+#     anything special.
+#
+#   * When Haskell libraries depend on other Haskell libraries, they
+#     MUST depend on, not build-depend on, such libraries. So if your
+#     package installs a library, you MUST NOT set
+#     BUILDLINK_DEPMETHOD.${PKG} to "build" in your buildlink3.mk
+#     file. Reason:
+#         1. Assume we have two libraries A and B, and B build-depends
+#            on A.
+#         2. We install package A.
+#         3. We then install package B, which build-depends on A.
+#         4. After that, a new upstream version of package A is
+#            released. We therefore update package A to the new version.
+#         5. Package B had a build-dependency on A, so pkgsrc assumes
+#            that it's still safe to use package B without
+#            recompilation of B. But in fact package B requires the
+#            very version of package A which was available when
+#            package B was compiled. So the installed package B is
+#            completely broken at this time.
+#

+#
+#   HASKELL_COMPILER
+#       Description:

+#       Possible values:
+#           ghc
+#       Default value:
+#           ghc

+# Package-settable variables:
+#
+#   HASKELL_ENABLE_LIBRARY_PROFILING
+#       Description:
+#           Whether profiling library should be built or not.
+#       Possible values:
+#           yes, no
+#       Default value:
+#           yes
