A little library to parse command line arguments.
The example resides in Main.hs.
To run it:
runhaskell Main.hs foo bar -v bip bap --help --name Fumbleton
The main parsing module is Args.hs.
To use it, one must define a custom set of options and handlers.
An example is shown in CLI.hs.
Both Args and CLI are then imported into Main.hs,
where the raw command line arguments are parsed with parse
(from Args). The result is a ParsedArgs record, that has
options and positional arguments.
