Purpose
Determine if all elements in two lists are present in both lists.
Package :gbbopen-tools
Module :gbbopen-tools
Arguments and values
| list-1 | A proper list | |
| list-2 | A proper list | |
| test | A function designator specifying a function object
of two arguments that returns a generalized boolean (default is
#'eql | |
| test-not | A function designator specifying a
function object of two arguments that returns a
generalized boolean (use of :test-not | |
| key | A function designator specifying a function object
of one argument, or nil (default is nil)

| boolean | A generalized boolean |
Returns
True if all elements in list-1 are also in
nil otherwise.
Description
Duplicate elements in either list are permitted, so the lengths
of
