  52  * Interface to provide extension points for options parsing.
  53  *
  54  * Currently, this is only used in the context of ICommandLineOptionsModule and
  55  * some other command-line handling, but it is declared in the options module
  56  * for the lack of a better place: most implementations of the interface are in
  57  * modules that do not otherwise depend on the commandline module.

  59  * \if libapi
  60  * Any code that wants to support these extension points needs to use
  61  * OptionsBehaviorCollection and call the methods there at appropriate points.
  62  * This is not (at least, not currently) integrated in any automatic way to the
  63  * actual Options object.
