description                 Scalable Library for Eigenvalue Problem Computations
long_description            SLEPc is a software library for the solution of large \
                            scale sparse eigenvalue problems on parallel computers. It is an \
                            extension of PETSc and can be used for either standard or generalized \
                            eigenproblems, with real or complex arithmetic. It can also be used for \
                            computing a partial SVD of a large, sparse, rectangular matrix.
