-- Portability : portable
--
-- This is a big module, but not very complicated. The code is very regular
-- and repetitive. It defines the command line interface for all the Cabal
-- commands. For each command (like @configure@, @build@ etc) it defines a type
-- that holds all the flags, the default set of flags and a 'CommandUI' that
-- maps command line flags to and from the corresponding flags type.
--
-- All the flags types are instances of 'Monoid', see
-- <http://www.haskell.org/pipermail/cabal-devel/2007-December/001509.html>
-- for an explanation.
--
-- The types defined here get used in the front end and especially in
-- @cabal-install@ which has to do quite a bit of manipulating sets of command
-- line flags.
--
-- This is actually relatively nice, it works quite well. The main change it
-- needs is to unify it with the code for managing sets of fields that can be
-- read and written from files. This would allow us to save configure flags in
-- config files.

-- | All flags are monoids, they come in two flavours:
--
-- 1. list flags eg
--
-- > --ghc-option=foo --ghc-option=bar
--
-- gives us all the values ["foo", "bar"]
--
-- 2. singular value flags, eg:
--
-- > --enable-foo --disable-foo
--
-- gives us Just False
-- So this Flag type is for the latter singular kind of flag.
-- Its monoid instance gives us the behaviour where it starts out as
-- 'NoFlag' and later flags override earlier ones.
