% Domain : Software Creation
% Problem : cond_pst_pivoted1_x_run_strict_ord_front2
% 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.
