SWEC is a program that automates testing of dynamic Web sites. It parses each HTML file it finds for links, and if those links are within the site specified, it will check that page as well. In addition to parsing and locating links, it will also parse the pages looking for known errors and report those. It will report if a page cannot be read (by either returning a 404, 500, or similar).
XHTML indent takes an XHTML file via standard input and outputs an indented version of the XML. It also adds comments to the end of closing tags so that you can quickly pick up on the opening tag without having to jump to the appropriate line. This does not convert bad code like HTML tidy does. It works with any XML formatted file, but has features designed for XHTML developers. This program works well as both a standalone tool or an external filter for a text editor.
Perl text2html is an HTML 4.01/CSS2 project that converts pure plain text files into very informative and professional looking HTML documentation pages. The text files require no markup whatsoever; just naturally written text. This utility predates the now similar Python-based asciidoc.
SynchroEdit is a browser-based document editor for use by multiple users simultaneously. It is a form of same-time, different-place groupware. It allows multiple users to edit a single web-based document at the same time, and it continuously synchronizes all changes so that users always have the same version.
PTM is a Perl/HTML hybrid language, written entirely in Perl, and similar to PHP in tag syntax. It allows for the ease of PHP-style inline code in your dynamic HTML documents, while supplying the power of Perl that many find to be sorely lacking in PHP. PTM's parser application, referred to as the PPA, acts as an Apache plugin, a standalone parser placed in the cgi-bin, or a command line parser (for debugging purposes), and is distributed for both Unix and Window platforms. Additionally, PTM wraps many variables common to PHP to ease the transition between PTM and PHP when switching back and forth.
