DESCRIPTION ^

HTML::TurboForm was designed as a small, fast and compact Form Class to use with catalyst in order to easily create any needed Form. I know there a quite a lot of classes out there which do the same but i wasn't quite content with what i found. They were either too slow or complicated or both.
