// This python module only contains the name of PETSC_DIR and PETSC_ARCH
// that PISM was compiled against.  These values are used to initialize
// petsc4py with the correct PETSc version when issuing an "import PISM"
// from within python.  We keep these values in a module separate
// from the main python bindings module 'cpp' because loading 'cpp' prior
// to initializing petsc4py was causing crashes upon exiting from python.
// I don't know what the cause was, but presumably some static code in 'cpp'
// was using PETSc, which had not yet been initialized. Now we can safely
// load this module, 'petsc_version' to initialize petsc4py, and then
// bring in the rest of 'cpp'.
