Allegro Common Lisp is a full ANSI Common Lisp (1994) implementation. It contains many extensions, including 32- and 64-bit native compilation, efficient built-in memory management, foreign functions (for interfacing with other languages), multiprocessing, UNICODE and locale support, XML/HTML parsers, a Web client and server, GTK+ interface (1.2 and 2.0), Java interface, OLE interface (Windows only), profiler, regular expressions, an XML RPC implementation, native Lisp RPC, sockets, DLL and shared library support, and more.
HTML-TEMPLATE is a portable library for Common Lisp that can be used to fill templates with arbitrary (string) values at runtime. It is intended to be used for HTML and is loosely modeled after the HTML::Template Perl module. It translates templates into efficient closures that can be re-used as often as needed, and uses an intelligent cache mechanism that allows templates to be updated while your program is running.
The lisp-cgi-utils is a software package for developing CGI scripts with Common Lisp. It implements a very basic HTTP/CGI interface (sending headers, getting GET/POST and environment variables) and offers tools for easier HTML generation with special support for handling HTML forms.
Lisp Blosxom is a port of the Perl Blosxom blogging engine to ANSI Common Lisp. Its goals are extensibility and speed. It's a filesystem-based blogging engine, which means that blog entries are just flat files on disk, although plugins can be written to extend or replace this behavior. The first line in the file is the title, while the remainder is the text of the body. Entry dates are taken directly from the filesystem's modification date for each entry. Furthermore, the structure of the blog is taken directly from the hierarchy of directories and files on disk.
