Re: [gobo-eiffel-develop] AP_STRING_LIST_OPTION?

[Colin A. <col...@ho...>]

It sounds to me like the two should be equivalent. Certainly I do not need =
a list of lists. But I suppose if people were to supply multiple uses of an=
 AP_STRING_LIST_OPTION, then this ought to be a list of lists. Is it possib=
