The test in 

  sandbox/misc/python

seems to run just fine. It is easy to check command line parsing in python 
just copy the last line of the print out from this test, and change any 
parmeters to test options passing:

  python test_params.py --bar 200 --foo 1.5 --pc amg \
            --solver.max_iterations 50 --solver.prec ilu \
            --solver.relative_tolerance -1.0 --solver.tolerance 1e-16

Note the illegal setting of the relative_toleance

You mean, only options with the prefix passed as the third parameters is 
parsed? Sounds like a nice feature!

Agree.

I will be offline for two weeks. 

Happy releasing!

I will comback in August, and be operational from the 10th.
