Toot is a stripped down and, hopefully, simplified version of Edi Weitz 's Hunchentoot HTTP server. It does not aim to be backwards compatible with anything and large swaths of Hunchentoot functionality have been cut out. Some of them may be put back someday. Use at your own risk. If it breaks you get to keep both pieces, etc. etc.
