-- See http://www.haskell.org/haskellwiki/Cabal/Developer-FAQ#Installing_manpages.
--
-- Based on pandoc's and lhs2tex's 'Setup.installManpages' and
-- 'postInst' hooks.
--
-- My understanding: 'postCopy' is run for `cabal copy`, 'postInst' is
-- run for `cabal inst`, and copy is not a generalized install, so you
-- have to write two nearly identical hooks.
--
-- Summary of hooks:
-- http://www.haskell.org/cabal/release/cabal-latest/doc/API/Cabal/Distribution-Simple-UserHooks.htm--
-- Other people are also confused:
--
-- * Bug: 'postCopy' and 'postInst' are confusing:
-- http://hackage.haskell.org/trac/hackage/ticket/718
--
-- * A cabal maintainer suggests using 'postCopy' instead of
-- 'postInst', because `cabal install` is `cabal copy` followed by
-- `cabal register`:
-- http://www.haskell.org/pipermail/libraries/2008-March/009416.html
-- Although that sounds desirable, it's not true, as the reply and
-- experiments indicate.
