This is a lisp interpreter written in php which can be access through a comfortable webinterface.
The functionality is based on a tutorial by Ron Deep.
The project has been started by Ralf D. Mueller.
pepperDoc is an automatic documentation compiler similar to javadoc, but for use on php sources.
It is very easy to use, because it's a commandline/binary, so you don't need to have a PHP-parser installed on your machine.
Currently win32 only.
