Picket

The Picket filter is a simple CherryPy filter for processing XSLT as a template language. It uses 4Suite to do the job.

What name is that?

Well, finding name for projects today is becoming almost a task per se. Picket came to my mind at one point (don't ask how...) so I picked it up.

Thanks to

The guys at 4Suite for all their help and support
