Reasons for this article:
- Getopt documentation is often too sparse to be useful
- Different languages have different pattern syntax (think C's "a:b:cd" getopt syntax)
- As with ScriptedMain, this behavior is as useful as it is obscure.
- getopt is not Google-friendly: the results tend to be C programs embedding the language in question.
The phone call example is just a quick example. I think we should define a more useful CLI example for each language.
pmath: Perform mathematical operations.
Examples:
Usage
