       gtst - test the consistency of source graphs


       gtst [options] [gfile] [lfile]


       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', on input only).

       Test the consistency of graph brol.grf:

           $ gtst brol.grf


       dgtst(1), gmap(1), gord(1), gout(1).
