A Quick and Dirty Guide to CLUE

This guide is a no-frills introduction to programming with the Common Lisp User Interface Environment (CLUE). CLUE is a high-level programming interface to the X Window System which extends (but does not supersede) the basic CLX interface. CLUE is also an object-oriented programming system based on the Common Lisp Object System (CLOS). Moreover, CLUE is a ``toolkit'' for constructing X user interfaces. As a result, CLUE is modelled closely on the standard toolkit used by C programmers, commonly known as Xt, or the X Toolkit.

All of these related systems are described in separate documents (these references are listed at the end of the guide), but we won't spend much time on them here. Read this guide and take the plunge into CLUE; you can dry off with the details later.
