If called without arguments, or passing your favourite editor as an argument, the program will launch an editor for the relevant file. After you've exited the editor, the file will be analyzed.

The default editor is emacs

If called with the '-test' string, the program will just analyze the file, without launching the editor first.

If called with the '-h' option, the program will just print a usage message.
