I was updating my documentation generator for pygtk (the one that tries to make the C reference docs for GTK look like docs for Python). It was taking a while to process with db2html (which uses Jade to convert from SGML to HTML), so I thought I would look at using DocBook/XML and DV's xsltproc, which I had heard ran a lot quicker.
Unlike other people's experiences, the docs ended up taking over twice as long to process with xsltproc compared to jade! I suppose this was to do with the size (about 1.9MB of of XML source), and the number of cross references (the doc generation script added a lot of xrefs). On other docs I tried, xsltproc seemed noticably better.
I also found out that White Christmas made with coco pops tastes pretty good.
