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.
