public @interface PositionalArguments

Used to annotate which field of a CommandLineProgram should store parameters given at the command line which are not options. Fields with this annotation must be a Collection (and probably should be a List if order is important). If a command line call looks like "cmd option=foo x=y bar baz" the values "bar" and "baz" would be added to the collection with this annotation. The java type of the arguments will be inferred from the generic type of the collection. The type must be an enum or have a constructor with a single String parameter.
