/**

|
* 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.
