Very nifty. I've now done the same for BoostBook, where one can configure the
DocBook XSL and DTD directories as such:

using boostbook : /home/gregod/Projects/share/docbook-xsl-1.60.1/
: /home/gregod/Projects/share/docbook-dtd-4.2/

I have one serious concern with the XML catalog generation I just checked in:
the command lines to "echo" can get pretty darn long, but I don't really know
how to break them up properly. Or perhaps there is a better way to generate
files than echo?
