Major coxeter update

The upgrades to coxeter’s hardware and software seem to have been successful.  Information about the new coxeter will be added to http://www.math.toronto.edu/admin/coxeter-upgrade.html as necessary.

Please let us know as soon as possible at requests@math.toronto.edu if you notice any problems.  It is better to let us know about problems early rather than wait for the start of the academic year when things are so busy that fixes may take a long time.  In particular please test the new TeX and LaTeX (using pdftex and pdflatex is the recommended way).
