Here is a simple script:

#!/usr/bin/env python
import os, sys

sys.path.insert(0, os.path.join(os.environ['PETSC_DIR'], 'python'))
sys.path.insert(0, os.path.join(os.environ['PETSC_DIR'], 'python',
'BuildSystem'))

import script

class ConfigReader(script.Script):
  def __init__(self):
    import RDict
    import os

    argDB = RDict.RDict(None, None, 0, 0)
    argDB.saveFilename = os.path.join(os.environ['PETSC_DIR'],
os.environ['PETSC_ARCH'], 'conf', 'RDict.db')
    argDB.load()
    script.Script.__init__(self, argDB = argDB)
    return

  def run(self):
    self.setup()
    framework = self.loadConfigure()
    mpi = framework.require('config.packages.MPI', None)
    print mpi.include, mpi.lib
    return

if __name__ == '__main__':
  print 'Starting'
  ConfigReader().run()
  print 'Ending'
