**BROKEN: TOO TIED TO OLD CCA LOADLEVELLER**

This was an alternative approach to testing, based on:

           tm5_test.py

       as a script:

           tm5_test.py -h file1.rc file2.rc

       or as a module (see test_tm6.py for an example). You had to link these
       files into your TM5 top directory, and call them from there.
       
       This approach gives you the option to use Unix's cmp and ncks (from NCO)
       to compare restart files, instead of ttb/bin/ttb_compare.py (which
       relies on not-always available 'numpy', 'netCDF4', 'pycdf', and 'pyhdf'
       python modules). See "method" variable in the comp_restart function.
       
       Also, it does not introduce new rc files, but uses command line
       arguments instead.
