[Tutor] ArgumentParser - Command Line arguments

[Mats Wichmann]

sorry, I made some thinkos when retyping these bits (no coffee yet :) ), 
just take the ideas, not the literal typing....


> parser.add_argument("file1", type=str, help='Input for sqlinvocation.log')
> parser.add_argument("--file2", nargs=1, help='patch file')
> 
> now you can run as all of these and it should work out:
> 
> python script.py somefilename
> python script.py --patch=patchfilename somefilename
> python script.py somefilename --patch=patchfilename
