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 the Getopt::Long::Descriptive
manpage, 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.

Differences from MooX::Options
Osprey is deliberately similar to the MooX::Options manpage, and
porting an app that uses MooX::Options to Osprey should be fairly
simple in most cases. However there are a few important differences.
