module to assist in writing commandline applications with OO modules

 CLI::Osprey is a module to assist in writing commandline applications with M*
 OO modules (Moose, Moo, Mo). With it, you structure your app as one or more
 modules, which get instantiated with the commandline arguments as attributes.
 Arguments are parsed using Getopt::Long::Descriptive, and both long and short
 help messages as well as complete manual pages are automatically generated.
 An app can be a single command with options, or have sub-commands (like git).
 Sub-commands can be defined as modules (with options of their own) or as
 simple coderefs.
