Ecf (Emacs Configuration Framework) is a versatile configuration package for Emacs. It is meant for users whose Emacs configuration has become so complex that it appears to be unmanageable. It enables you to write and load the configuration for individual Emacs packages in pieces. You can use it to setup some autoloads for a package when you start Emacs and then do extra configuration after the package has loaded. This speeds up your Emacs startup without compromising your ability to do complicated things.
ics.el is a comint based Emacs major mode for handling the text portion of communications with internet chess servers such as FICS and ICC. It is written in Emacs-Lisp and works best in conjunction with a graphical interface such as Xboard. It handles colour highlighting and "buttonisation" (making certain portions of text active so that, for example, you can challenge opponents with a single mouse click) as well as command recall and editing and automation of commands based on regexps seen in the ICS output, all highly customisable using Emacs lisp.
xslide is a major mode for (X)Emacs for editing XSL Stylesheets. Its features include an XSL customization group for setting some variables; an initial stylesheet which is inserted into empty XSL buffers; a "template" menu for jumping to template rules, named templates, key declarations, and attribute-set declarations in the buffer; an "xsl-process" function that runs an XSL processor and collects the output; syntax highlighting; an "xsl-complete" function for inserting element and attribute names; an "xsl-insert-tag" function for inserting matching start- and end-tags; automatic completion of end-tags; automatic indenting of elements with user-definable indentation step; and a comprehensive abbreviations table.
Gnutran is a simple, Emacs-based front-end to a number of machine translation engines available on the Web. It can send emacs buffers to a translation engine, request a translation (e.g. English to Portuguese) and display the result on a new window. GNUTRAN interoperates with emacs-based email agents such as VM-Mail and features a highly configurable interface, allowing easy set up of new translation pairs through Emacs' customization interface.
