We propose FORTRAN subroutines for approximately solving the feedback vertex and arc set problems on directed graphs using a Greedy Randomized Adaptive Search Procedure (GRASP). Implementation and usage of the package is outlined and computational experiments are reported illustrating solution quality as a function of running time.
