process(
argv =
sys.argv,
* * commands)
Accept a set of commands and process according to command line options.
The typical call will start with the name of the processor to be executed,
followed by a set of parameters, followed by non-parameter arguments.
All parameters are either of the form 'name=value', or '--name=value'.
The first form expects 'value' to be valid python, the second a string.
The remaining non-parameter arguments are associated with the 'input'
parameter.
Once this initialization is done, the named command's 'process' method
is executed.
