more stylesheet fun

Try running the stylesheet below for an all-in-one look at
install-time (or yum-time) package groups.

Sample output: http://www.cse.ogi.edu/~heinlein/comps.html

If you save the stylesheet as, say, comps2html.xsl, then invocation is
simple:

  xsltproc -o comps.html --novalid comps2html.xsl comps.xml
