mdocml is a suite of tools for compiling "-mdoc", the roff macro package of choice for BSD manual pages, and "-man", the predominant historical package for UNIX manuals. The mission of mdocml is to deprecate groff, the GNU roff implementation, for displaying -mdoc pages whilst providing token support for -man.
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.
