I've been toying with the idea of converting my
scribbles into DocBook (it's currently in
texinfo), so I've started trying to put together a
DocBook toolchain. The core tools seemed easy enough to get hold of (the
Fink packages covered most everything), but setting up
a makefile for the full system has been quite complicated.
I'm not too convinced by the results as yet, but I haven't really gone too deeply into the markup and the stylesheets. On the plus side, at least the standard references are available online to help out (although if I do shift to DocBook, I'll probably get around to getting the dead tree versions anyway).
