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.
The DocBook Authoring and Publishing Suite (DAPS) provides a tool set for easy creation and publication of DocBook sources on Linux. It lets you create HTML (including Webhelp), PDF, EPUB, man pages, and other formats with a single command. It automatically takes care of validating and filtering (profiling) your sources and automatically converts images into a format best suited for the output format. You can easily create profiled source tarballs for translation or review. DAPS supports authors by providing linkchecker, validator, spellchecker, and editor macros. It is well suited to manage large documentation projects with multiple authors using the DAPS docmanager.
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.
