Source cross reference + colourizer (PyXR is no more?)

[Roger Binns]

I have been a happy user of PyXR which colourizes source to HTML and
also cross references it.  Here is an example of the output:

  http://bitpim.org/pyxr/c/projects/bitpim/analyser.py.html

Unfortunately the author and his site appears to have gone AWOL for
quite a while.  It used to be:

  http://www.cathoderaymission.net/~logistix/python/pyxr.html

Does anyone know what happened to the author?  Are there any
maintained alternatives to PyXR?
