module Boson
  # This library takes a module or class as a library's name and loads its class methods
  # as commands. If no commands are given it defaults to loading all of its class methods
  # as commands. The only method callback (see Loader) this library calls on the
  # original module/class is config().
  #
  # Example:
  #  >> load_library Math, :commands=>%w{sin cos tan}
  #  => true
  #
  #  # Let's brush up on ol trig
  #  >> sin (Math::PI/2)
  #  => 1.0
  #  >> tan (Math::PI/4)
  #  => 1.0
  #  # Close enough :)
  #  >> cos (Math::PI/2)
  #  => 6.12323399573677e-17
