--
-- This is the command line front end to the Simple build system. When given
-- the parsed command-line args and package information, is able to perform
-- basic commands like configure, build, install, register, etc.
--
-- This module exports the main functions that Setup.hs scripts use. It
-- re-exports the 'UserHooks' type, the standard entry points like
-- 'defaultMain' and 'defaultMainWithHooks' and the predefined sets of
-- 'UserHooks' that custom @Setup.hs@ scripts can extend to add their own
-- behaviour.
--
-- This module isn't called \"Simple\" because it's simple.  Far from
-- it.  It's called \"Simple\" because it does complicated things to
-- simple software.
--
-- The original idea was that there could be different build systems that all
-- presented the same compatible command line interfaces. There is still a
-- "Distribution.Make" system but in practice no packages use it.

  -- This has caused hard-to-debug failures in the past (#5368), so we
  -- detect some cases early and warn with a clear message. Windows's
  -- use of backslashes is problematic here, so we'll switch to
  -- slashes, but we do still want to fail on backslashes in POSIX
  -- paths.
  --
  -- TODO: We don't check for colons, tildes or leading dashes. We
  -- also should check the builddir's path, destdir, and all other
  -- paths as well.
