cas release 0.15

by Adam Stokes

A new release of cas is now available. Updates/Enhancements: - Replaced func with paramiko. This gives the user the ability to run cas as a user other than root. (cas-admin is still required to run as root, however). - Update documentation to help you along with the new configuration settings that allows you to more finely tune cas. - Some speed up improvements like using a local copy of an installed debug kernel if exists rather than extracting a second debug kernel. Its been submitted to testing repo's for both f10/11 and is awaiting bodhi to finalize the push. Please test and report your experiences on the list. Thanks -- __ __ .-----.| |_.-----.| |--.-----.-----. |__ --|| _| _ || <| -__|__ --| |_____||____|_____||__|__|_____|_____| .----------------------------------.
