ACDK ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but instead of using Basic/C# or Java as programming language, it bases C++ as core implementation language. ACDK implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml and more, as well as technologies like flexible Allocator/Garbage Collection, Threading and Unicode. With the extensions of ACDK C++ objects are available for reflection, serialization, aspect oriented class attributes and [D]ynamic [M]ethod [I]nvocation. This DMI act as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, VBScript) and standard component technologies (CORBA, COM+).

ACL2 ACL2 is a mathematical logic and a mechanical theorem prover to help you reason in the logic (which is a subset of applicative Common Lisp). The theorem prover is an ``industrial strength version of the Boyer-Moore theorem prover, Nqthm. Users can build models of all kinds of computing systems in ACL2, just as in Nqthm, even though the formal logic is Lisp. Once you've built an ACL2 model of a system, you can run it and use ACL2 to prove theorems about the model.

CMUCL CMUCL is a free, high performance implementation of the Common Lisp programming language which runs on most major Unix platforms. It mainly conforms to the ANSI Common Lisp standard. CMUCL provides a sophisticated native code compiler; a powerful foreign function interface; an implementation of CLOS, the Common Lisp Object System; which includes multimethods and a metaobject protocol; a source-level debugger and code profiler; and an Emacs-like editor implemented in Common Lisp.

Clisp ANSI Common Lisp is a high-level, general-purpose programming language. GNU CLISP is a Common Lisp implementation by Bruno Haible of Karlsruhe University and Michael Stoll of Munich University, both in Germany. It mostly supports the Lisp described in the ANSI Common Lisp standard. It runs on most GNU and Unix systems (GNU/Linux, GNU/Hurd, FreeBSD, NetBSD, OpenBSD, Solaris, Tru64, HP-UX, BeOS, IRIX, AIX, Mac OS X and others) and on other systems and needs only 4 MB of RAM. The user interface comes in English, German, French, Spanish, Dutch, Russian and Danish, and can be changed during run time. GNU CLISP includes an interpreter, a compiler, a debugger, CLOS, MOP, a foreign language interface, a socket interface, i18n, fast bignums, arbitrary precision floats and more. An X11 interface is available through CLX, Garnet, CLUE/CLIO. GNU CLISP runs Maxima, ACL2 and many other Common Lisp packages.

Common Lisp SQL 'CLSQL' is an SQL database interface for Common Lisp. It provides object-oriented and functional access methods to the underlying database, which can be one of MySQL, ODBC, PostgreSQL, or SQLite. It uses the Unified Foreign Function Interface (UFFI) and thus supports the CMU Common Lisp, Steel Bank Common Lisp, Allegro Common Lisp, OpenMCL, and Lispworks implementations.

Doxymacs 'doxymacs' is an elisp package designed to make using and creating Doxygen easier for Emacs users. It can look up documentation for classes, functions, members, etc in the browser of your choice, fontify Doxygen keywords, and automagically insert Doxygen comments in JavaDoc, Qt, or C++ style. You can also create your own style via templates.

ECB 'ECB' is a source code browser for Emacs. It displays windows that can be used to browse directories, files, and file contents like methods and variables. It supports source code parsing for languages like Java, C, C++, Elisp, Scheme, Perl, TeX, LaTeX, etc. It also offers an (optional) permanent "compile window" at the bottom of the emacs frame, which displays all help and compile output. The rest of the frame is called the "edit area", which can be divided into several edit windows that are used for editing the sources. Deleting some of the edit windows neither destroys the compile window nor the browsing windows.

Elib Elib is designed as a collection of useful routines that don't have to be reinvented each time a new program is written. It contains code for container data structures, minibuffer and string handling functions missing in standard Emacs, and routines for handling lists of cookies in a buffer. This project was a GNU package. It has since been decommissioned and is no longer developed.

Emacs Common Lisp Emacs Common Lisp is an implementation of Common Lisp, written in Emacs Lisp. The implementation provides a Common Lisp environment, separate from Emacs Lisp, running in Emacs. It does not intend to extend Emacs Lisp with Common Lisp functionality; however, Emacs Lisp functions can call Common Lisp functions and vice versa.

Enotes 'enotes' is a small GNU Emacs script to handle appointments. It stores a list of notes, each with a title, a date, a warning date, and optionally a long description and a reference file. A window pops up when a warning time is reached. It is simple (more than calendar and others), yet reliable and very practical
