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.

notes       "Add the following line to your .bash_profile if you plan to use\
            the PETSC makefile rules in $prefix/lib/petsc/conf: \n\
            \texport PETSC_DIR=${prefix}/lib/petsc"
