> Parse command-line arguments.

|
- Parse optional `verbose`/`version` flags with shorthands:
|
|
|
|
`getopt {{[-o|--options]}} vV {{[-l|--longoptions]}} verbose,version -- --version --verbose`
|
|
|
|
- Add a `--file` option with a required argument with shorthand `-f`:
|
|
|
|
`getopt {{[-o|--options]}} f: {{[-l|--longoptions]}} file: -- --file=somefile`
|
|
|
|
- Add a `--verbose` option with an optional argument with shorthand `-v`, and pass a non-option parameter `arg`:
|
|
|
|
`getopt {{[-o|--options]}} v:: {{[-l|--longoptions]}} verbose:: -- --verbose arg`
|
|
|
|
- Accept a `-r` and `--verbose` flag, a `--accept` option with an optional argument and add a `--target` with a required argument option with shorthands:
|
|
|
|
`getopt {{[-o|--options]}} rv::s::t: {{[-l|--longoptions]}} verbose,source::,target: -- -v --target target`
