-- This module deals with registering and unregistering packages. There are a
-- couple ways it can do this, one is to do it directly. Another is to generate
-- a script that can be run later to do it. The idea here being that the user
-- is shielded from the details of what command to use for package registration
-- for a particular compiler. In practice this aspect was not especially
-- popular so we also provide a way to simply generate the package registration
-- file which then must be manually passed to @ghc-pkg@. It is possible to
-- generate registration information for where the package is to be installed,

-- This module does not delegate anything to the per-compiler modules but just
-- mixes it all in in this module, which is rather unsatisfactory. The script
-- generation and the unregister feature are not well used or tested.
