commit 54fe6d369d18680e53d3f60be3dbdb42356bd94f
Author: Richard W.M. Jones <rjones at redhat.com>
Date:   Wed Jun 10 14:06:03 2015 +0100

    p2v: Add proper test for command line parsing.
    
    This also adds a couple of deliberately undocumented (and unsupported)
    command line parameters to make testing simpler:
    
    p2v.skip_test_connection  - don't try to test the connection
    p2v.dump_config_and_exit  - after parsing command line, print it and exit
    
    This updates commit 716244c33718c866edce9e7ee8f21ee612f53337.
