%description
This software package implements the thick-restart Lanczos method.
It can be used on either a single address space machine or a distributed
parallel machine. The user can choose to implement or use a matrix-vector
multiplication routine in any form convenient. Most of the arithmetic
computations in the software are done through calls to BLAS and LAPACK.
