Help is given as structure listing command and their parameters in a
short/compressed form.

help        = dict (name -> command)
name        = string
command     = list (description options arguments)
description = string
options     = list (option...)
option      = dict (name -> description)
arguments   = list (argument...)
argument    = list (code name description)
code in {
     +		<=> required
     ?		<=> optional
     +*		<=> required splat
     ?* 	<=> optional splat
}

The conversion of this form into a help text, or other structure is
outside of the scope of xo/cmdr
