description                 Portable, Extensible Toolkit for Scientific Computation
long_description            PETSc, pronounced PET-see (the S is silent), is a suite \
                            of data structures and routines for the scalable (parallel) solution \
                            of scientific applications modeled by partial differential equations. \
                            It employs the MPI standard for all message-passing communication.
