public class OptionGroup

A `GOptionGroup` struct defines the options in a single group.

The struct has only private fields and should not be directly accessed.

All options in a group share the same translation function. Libraries which need to parse commandline options are expected to provide a function for getting a `GOptionGroup` holding their options, which the application can then add to its OptionContext.
