%description
This package contains a library that enables exploration of
combinatorial issues related to Coxeter groups and Hecke algebras, with
a particular emphasis on the computation of Kazhdan-lusztig polynomials
and related questions.

%description    tools
Coxeter is a program for the exploration of combinatorial issues related
to Coxeter groups and Hecke algebras, with a particular emphasis on the
computation of Kazhdan-lusztig polynomials and related questions.  It is
not a symbolic algebra system; rather, it is an interface for accessing
a direct C++ implementation of the concept of a Coxeter group.
