McCLIM, an implementation of the "Common Lisp Interface Manager CLIM II Specification", is a portable and high-level user interface management system toolkit for Common Lisp. It has a powerful presentation model which allows us to directly link the visual representation of an object to its semantics. It has several high-level programming capabilities that enable us to develop a user interface conveniently; including formatted output, graphics, windowing and commands that are invoked by typing text, keyboard shortcuts or clicking a mouse button. McCLIM works with Allegro CL, Clozure CL, CLISP, CMUCL, Embeddable CL, the Scieneer CL Common-lisp, SBCL and the LispWorks implementations. Right now the only backend supported by McCLIM is CLX, which ties it to the Xserver on the host system. Any platform capable of running Xserver may run McCLIM applications.
