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.
instmake allows you to instrument builds with GNU Make and then analyze what happened during those builds. It saves a very detailed build log and has reports to analyze those records. The reports provide you better insight into the build, allow you to find race conditions, and to analyze the parallelism of the build.
Source Ruckus Linux is an embeddable, robust Linux meta-distribution. It's a collection of build tools, source packages, scripts, and documentation all ready to be built into a Linux distribution. It can be used out-of-the-box, but its real strength lies in being used as a base for your own distribution. In other words, it exists purely to be forked, although it can be used as-is.
autober is a language for generating BER decoders. It's different from an ASN.1 compiler in that it's much simpler and it only deals with BER-encoded messages. It is intended for smart card and RFID applications where much of the data stored on these devices is, in-fact, BER-encoded TLV data. The language is designed to be very similar to the template definitions found in the specifications for smart card and RFID applications.
