Been looking for what may be missing for documentation toolchain in Tuma MinGW... umm no not L4t3X! too big (even bigger than the whole packages). It's direct html to pdf converter and has to be open source too. So there would be Ghostscript, OpenJade, Poppler, Doxygen, DjVulibre, HTMLDoc and some others.. great
HTMLDoc is a quite capable converter with extensive command line features. I've taken the svn snapshot which is r1707 (not sure if it still developed). The svn version have somewhat unfinished? support for CSS and pdf bookmark too.
It need some patch (included in the download) for building with mingw instead of M$VC and minor modification to make it portable (no registry/installation needed)
Binaries for Windows 32bit:
Extract anywhere and you're ready to go!
HTMLDoc 1.9 r1707 (console only)
HTMLDoc 1.8.27 (console and gui)
When using the command line version, the folder where htmldoc extracted need to be put in PATH environment.
