Drupal integration of Roundabout jQuery plugin by FredHQ (http://fredhq.com/projects/roundabout/)

Adds element validators to Drupal that that fit into Drupal's form API. Instead of writing the (almost) same _validate function over and over, you can use the element's #element_validate property when building a custom form.

What is Role Export

The Role Export module allows roles to have machine_names and generates a unique role id (rid) based off of the machine_name.

Because of this unique rid there is no need to create plugins per contrib module that use the rid in their export code, such as Views, Ctools, Rules, etc.
