MkDoc is a C and C++ code documentation tool. It parse complex code and still produces clear documentation for developers and library users. Unlike most code generation tools, it does not simply write generated code documentation with pieces of user text inside. Instead it handles plain documentation files with sections and other constructs (like Texinfo or LaTeX) and inserts pieces of generated code documentation on request. Thus it does not enforce any way of structuring your document. It has been designed to parse advanced C++ constructs including class inheritance, template specialization, and template instantiation. XHTML, Texinfo, LaTeX, and DocBook output formats are supported.
zpub is a server to collaboratively work on DocBook-based documentation. Editors modify the XML sources with their preferred editor and submit their changes via Subversion. zpub renders the files centrally to various output formats, optionally notifies other editors, provides an archive of all previous revisions of the document, and supports a simple sign-off workflow. The documentation and user interface is currently only available in German.
Thot takes as input text in a wiki-like format and outputs results for different formats: HTML, Latex, DocBook, and PDF. Although delivered with only one input language (Dokuwiki format), Thot is very versatile and easy to extend. For example, the initial version allows you to embed a document description from different entities: source language, GraphViz DOT graphs, Latex math, etc.
RTextDoc is a text editor with proofreading. It is designed for typesetting professional research papers and manuals using the LaTeX, AsciiDoc, and DocBook markup languages. It includes on-the-fly spelling and grammar checking, syntax highlighting, bracket matching, folding, a document structure browser for sections and labels, bookmarks, a manager for LaTeX symbols, WYSIWYG equation editor, and integrated BibTex database manager.
