Using docopt to easily implement Python command line parameter processing

A python library in front of docopt, you can use __doc__ to implement command-line parameter processing, very simple to use; I also happen to have the need to add or remove testsuite/testcase at the command line, so I wrote a demo file.

PS: I just found that docopt has not updated for 2 years, OK, still can continue to use it.

Go directly to my demo program
