35        MyApp->new_with_options( UseAmmonia => 1, UseChlorine => 1 );
36        # generates Error
37        # More than one attribute from mutexgroup NonMixableCleaningChemicals('UseAmmonia','UseChlorine') *cannot* be specified
38
39        MyApp->new_with_options();
40        # generates Error
41        # One attribute from mutexgroup NonMixableCleaningChemicals('UseAmmonia','UseChlorine') *must* be specified
42
43        MyApp->new_with_options( UseAmmonia => 1 );

DESCRIPTION

50       This plugin adds mutually exclusive options to your application. In the
51       current implementation, all defined MutexGroups *must* have exactly one
52       initialized option. This means that there is an implicit requiredness
53       of one option from each MutexGroup.
