Missing information about how to use getoptions

[shpoont]

Overall, it looks like a good tool, with many features, but learning how to use it is very time intensive. While there are some examples, there is hardly any explanation in the documentation.

I still have some questions unanswered, for example

• What is the format of each of the following: "setup", "msg", "flag", "option", "param", and "disp"? Any others?
• What is "mode"? How can it be used?
• What is the difference between "parameter" and "option"?
• How do I define the required parameters?

In addition, while getoptions looks useful, it is difficult to understand how it works from the code.
