       The  gtst  program  checks, in a sequential way, the consistency of a Scotch source graph and, in case of
       success, outputs some statistics regarding edge weights, vertex weights, and vertex degrees.

       It produces the very same results as the dgtst(1) program of the  PT-Scotch  parallel  distribution,  but
       unlike this latter it cannot handle distributed graphs.

       Source graph file gfile can only be a centralized graph file. The resulting statistics are stored in file
       lfile.  When  file  names  are  not  specified,  data is read from standard input and written to standard
       output. Standard streams can also be explicitly represented by a dash '-'.

       When the proper libraries have been included at compile time, gtst can directly handle compressed graphs,
       both as input and output. A stream is treated as  compressed  whenever  its  name  is  postfixed  with  a
       compressed  file  extension,  such  as  in 'brol.grf.bz2' or '-.gz'. The compression formats which can be
       supported are the bzip2 format ('.bz2'), the gzip format ('.gz'), and the lzma format ('.lzma').

       Test the consistency of graph brol.grf:

           $ gtst brol.grf
