The Common Lisp Interface Manager (CLIM) is a powerful Lisp-based toolkit that provides a layered set of portable facilities for constructing user interfaces. The CLIM User Guide is intended for CLIM programmers who are looking for material arranged by concept. The Guide, based on the CLIM II Specification, is a complete reference for the LispWorks ® version of CLIM. Each chapter explains a key aspect of CLIM and includes summaries of conditions, constants, functions, macros, and presentation types that pertain to the particular topic, as well as many examples of code.
