Javuh is a registry of organized PHP classes. The classes share a common debugging structure and design method. The classes are meant to be extended and used together.
Javuh features an object modeling environment called Psychoo, which uses a dictionary-like file format to describe a site schema. From the schema, databases, HTML forms, and PHP classes are generated. Hopefully, this decreases development time by reducing the mundane work. Application of Don't Repeat Yourself in the PHP kingdom.
Javuh also includes a number of other classes for internet protocols (HTTP, Gnutella, Buggoo UDP debugging protocol), parsing (XML, Python pickles), database abstraction (MySQL, PgSQL, DbTcp), and session stuff. The library set is currently quite stable and used on a number of sites. It's PHP code, so it's not a terribly big deal, but saves us a lot of time generally.
