Building dia from source

[Bruce Dubbs <bruce dubbs gmail com>]

I downloaded and built dia from the tar.gz file and it works
beautifully.  One question.  How do you build the html files?  All the
tarball has is xml files.  'make html' does nothing (but errors on the
po subdirectory).

I was able to download the html files one by one from
http://dia-installer.de/doc/en/index.html, but I'd like to know how dia
builds html from their xml files.

Thanks for a great product.
