//
// The entry point SaveAllSettings() is called by the wizard when
// it is time to save the answer file (and possibly the .udf and
// sample batch script).
//
// The global vars GenSettings, NetSettings, etc. are examined
// and we decide what [Section] key=value settings need to be
// written.
//
// If you're adding a page to this wizard, see the function
// QueueSettingsToAnswerFile().
