 =head2 The enum type
 
 The C<enum> type can be used for an option or argument that takes a limited number of named values, in much the same was as C/C++ enums are used. For an option or argument of type C<enum> you must specify the possible values that the enum can take using the C<==enum-value> keyword. These may optionally have a separate description per value. If any value has an individual description, they all must.
