I would strongly advise anyone trying emacs CVS if they use
debian/ubuntu - you have to really know what you are doing to get it
installed. Despite advice from ##emacs on irc, I never got it working -
the cvs version clashes with the debian install packages.

Having said that I use emacs-snapshot from synaptic and I got
htmlmodedelux working. The jury is out on whether its better than c-mode
for php and html-helper-mode, but it works.
