HappyDoc is a tool for extracting documentation from Python source code. It differs from other such applications by the fact that it uses the parse tree for a module to derive the information used in its output instead of importing the module directly. This allows the user to generate documentation for modules which need special context to be imported.
LyX is a document processor that encourages an approach to writing based on the structure of your documents, not their appearance. It is intended for people people who write and want their writing to look great without tinkering with formatting details, font attributes, or page boundaries. On screen, it looks like any word processor, but it uses the TeX engine for printed output and producing richly cross-referenced PDFs. It is stable and fully featured.
PyleWiki is a WikiClone written entirely in Python that allows a group of people to collaboratively edit a tree of webpages using nothing but their browser and a simple, text-based markup language. This particular WikiClone has a few extensions to the original: attachments to pages, user authentication (primitive), and the use of templates for page styling among others.
SGMLtools-Lite is the successor of SGMLtools. It is a set of Python and DSSSL scripts which makes interaction with Jade in order to process (mostly DocBook) SGML files a breeze, and is easy to extend with custom processing instructions. Out of the box, SGMLtools-Lite knows how to convert DocBook to HTML (2 styles), JadeTeX, DVI, RTF, PS, PDF, plain text, and PalmOS iSilo format. It also comes with a conversion script to convert "old" LinuxDoc documents to DocBook.
Synopsis is a multi-language source code introspection tool that provides a variety of representations for the parsed code to enable further processing such as documentation extraction, reverse engineering, and source-to-source translation. It provides a framework of C++ and Python APIs to access these representations and allows Processor objects to be defined and composed into processing pipelines, making this framework very flexible and extensible.
Txt2tags converts a text file with minimal markup to HTML, XHTML, SGML, DocBook, LaTeX, Lout, Man page, Creole, Wikipedia, Google Code Wiki, PmWiki, DokuWiki, MoinMoin, MagicPoint, PageMaker, AsciiDoc, or ASCII Art. It is simple and fast and features automatic TOC, macros, filters, include, tools, GUI, CLI, and Web interfaces, translations, and extensive documentation.
Tixapps is a suite of development applications that run with Tcl/Tk or Python, using the Tix widget set. Applications currently included in Tixapps are tixinspect (an inspector for Tix/Tk applications), tixdebug (a debugger to work with tixinspect), and tixinfo (an info browser for GNU documentation).
