I just noticed this post to the arXiv. Is Meinholf Geck in touch with
Sage?

We introduce the computer algebra package {\sf PyCox}, written
entirely in
the {\sf Python} language. It implements a set of algorithms - in a
spirit
similar to the older {\sf CHEVIE} system - for working with Coxeter
groups and
Hecke algebras. This includes a new variation of the traditional
algorithm for
computing Kazhdan-Lusztig cells and $W$-graphs, which works
efficiently for all
groups of rank $\leq 8$ (except $E_8$). Our experiments suggest a re-
definition
of Lusztig's "special" representations which, conjecturally, should
also apply
to the unequal parameter case.
