% Domain   : Software Creation
% Problem  : cond_pr_works_on_pairs_x_swap_ends
% Version  : [Wei00] axioms.
% English  : Find components in a software library that match a given target
%            specification given in first-order logic. The components are
%            specified in first-order logic as well. The problem represents
%            a test of one library module specification against a target
%            specification.
