-'''A simple transformation script for the introduction of OpenMP with PSyclone.
-In order to use it you must first install PSyclone. See README.md in the
-top-level psyclone directory.
-
-Once you have PSyclone installed, this script may be used by doing:
-
- >>> psyclone -s ./omp_levels_trans.py traldf_iso.F90
-
-This should produce a lot of output, ending with generated
-Fortran.
