  checking an options presence (Rob Gleeson)
* Ensure `execute` passes command arguments to the block
* Support for summary and description (Denis Defreyne)

  block
* Allow passing a class name to `on` to be used as an `:as` option. ie:
  `on :people, 'Some people', Array`

  options

  start with an alphabet character
* Bugfix: Allow a Range to accept a negative Integer at either end

1.5.5 (2011-05-03)
------------------

* Bugfix: only attempt to extract options prefixed with `-`

1.5.4 (2011-05-01)
------------------

* Bugfix: `parse!` should not remove items with the same value as items used
  in option arguments. Fixes #22 (Utkarsh Kukreti)

------------------

* Bugfix: Use integers when fetching array indexes, not strings
