description         A package for unstructured graph partitioning

long_description    METIS is a set of programs for partitioning graphs and \
                    for producing fill reducing orderings for sparse \
                    matrices. The algorithms implemented by METIS are based \
                    on the multilevel graph partitioning scheme described \
                    in \[KK95a\] and \[KK95e\]. METIS provides high quality \
                    partitions, is extremely fast, and produces low fill \
                    orderings.
