This update is quite involved for a minor version update.
1. I had to change the source from Sourceforge to Github.
2. I manually specify the autoconf pre-configuration steps. This seems to be
necessary, but is there a better, more canonical way?
3. I had to add the docbook dependency and tinker around with substitutions,
because the original files would pull sources from an online repository. Please
have a look!
Thanks for your comments.
Cheers.
