[ruby/optparse] More on tutorial (#16)
- Added example in "Argument Converters"; it doesn't seem right for a tutorial to have no example in one of its topics (and instead just linking elsewhere).
- Added section "Command-Line Abbreviations."
- Added section "Keyword Argument into," showing how to:
- Collect options.
- Check for missing options.
- Provide option defaults.
