Documentation and examples for PETSc

 PETSc is the "Portable Extensible Toolkit for Scientific Computation", 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. Several sample
 scientific applications, as well as various papers and talks, demonstrate the
 features of the PETSc libraries.
