Initial Package Version: 4.0.11.1
Origin: Tushar Teredesai
Upstream Status: Not sent.
Description: Improves on the naming conventions for usernames and groupnames.
  * Allows usernames to contain Uppercase letters
  * Increases the groupname length to 32 (same as the username)
I created these primarily for the pkg_user hint which benefits from this
relaxed (but not non-standard) naming conventions.
