[Catalyst] Which Form Validation Libs?

[Eric Berg]

I see that there are a number of form validation libraries that purport 
to work with Catalyst.  I've been using CGI::Formbuilder for years and 
have been relatively happy with it.

I need something for my new Catalyst app.  I have already created my 
forms in my TT templates, but I need validation for most of the regular 
stuff, including zip codes, states, credit card info, etc.

You guys got any  recommendations?

Thanks.

Eric
