ILISP is a package that is designed to integrate various Lisp implementations (mostly Common Lisp systems and various Scheme dialects, including Guile) within Emacs (or XEmacs). ILISP runs an inferior Lisp process (in Emacs parlance) and provides a specialized set of commands, key bindings, and menus to ease the interaction with it. ILISP commands access the underlying Lisp process and provide ways to make the editing, compilation, and execution of Lisp programs much easier.
HO-CVS is a version control system based on MetaCVS. In addition to the features of MetaCVS, it features module level versioning, the ability to reference every version (since there is a tag after every commit, which is extremely useful but slow), complex versions like #v1.2.3 designed to carry information about the change, operation hooks, and a somewhat powerful log command.
CoMa provides a uniform configuration mechanism for items. CoMa is similar to autoconf, but without the auto part. It is intended to be used in component-based development where different software pieces are used in the context of more than one application or version of the same application. It provides a way to configure items and query or validate their configuration. At present, it works best with HO-CVS, but it can still work with pure CVS, albeit with some loss of convenience.
Common Lisp Quick Reference is a booklet with short descriptions of the thousand or so symbols defined in the ANSI standard. It comes with a comprehensive index. It is written in LaTeX and formatted for printing on both A4 and letter paper. After folding the sheets lengthwise, they can easily be turned into a handy booklet.
Steel Bank Common Lisp is a development environment for Common Lisp, with excellent support for the ANSI standard: garbage collection, lexical closures, powerful macros, strong dynamic typing, incremental compilation, and the famous Common Lisp Object System (multimethods and all). It also includes many extensions, such as native threads, socket support, a statistical profiler, programmable streams, and more. These are all available through an integrated, interactive native compiler which feels like an interpreter. SBCL is unique in being a multiplatform native compiler which bootstraps itself completely from source, using a C compiler and any other ANSI Common Lisp implementation.
