The CMU Common Lisp project is no longer funded, so only minimal support is
being done at CMU. There is a net community of CMU Common Lisp users and maintainers
who communicate via comp.lang.lisp and the cmucl-bugs@cs.cmu.edu
cmucl-imp@cons.org
mailing lists.
This manual contains only implementation-specific information about CMU Common Lisp. Users will also need a separate manual describing the Common Lisp standard. Common Lisp was initially defined in ıCommon Lisp: The Language, by Guy L. Steele Jr. Common Lisp is now undergoing standardization by the X3J13 committee of ANSI. The X3J13 spec is not yet completed, but a number of clarifications and modification have been approved. We intend that CMU Common Lisp will eventually adhere to the X3J13 spec, and we have already implemented many of the changes approved by X3J13.
Until the X3J13 standard is completed, the second edition of Common Lisp: The Language 2 is probably the best available manual for the language and for our implementation of it. This book has no official role in the standardization process, but it does include many of the changes adopted since the first edition was completed.
In addition to the language itself, this document describes a number of useful library modules that run in CMU Common Lisp. Hemlock, an Emacs-like text editor, is included as an integral part of the CMU Common Lisp environment. Two documents describe Hemlock: the ıHemlock User's Manual, and the ıHemlock Command Implementor's Manual.
