GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
This C code module gives the Apache 1.3.x HTTP server the ability to correctly negotiate content types for XHTML documents. Currently these are sent as text/HTML for most Web sites. This gives maximum compatibility among older Web clients, but is not recommended practice according to the W3C.
HTML Include solves the problem that the Hypertext Markup Language doesn't know a command for including other files into a source file. It uses specially styled comments to refer to other files, which will be inserted at this position. Unlike to the well known Server Side Include mechanism, this tool pre-processes the HTML files, resulting in files that have all referenced source files directly embedded. Thus it does not depend on any Web-server for correct appearance. As a bonus, HTML Include also writes the current date to the "last modification" line and brower meta, which you usually forget (or do not bother) to update.
FCKosc puts a WYSIWYG HTML editor into OsCommerce's admin section in product descriptions, newsletters, and the main page. FCKosc is built on FCKeditor. This editor will work in IE 5.5+, Firefox 1.0+, Mozilla 1.3+, and Netscape 7+. FCKosc requires no changes to OsCommerce's database. Minimal changes were made to the files, which helps reduce the posibility of conflicts with other additions. FCKosc is easy to upgrade as new versions are released.
