NAME
       gtst - test the consistency of source graphs

SYNOPSIS
       gtst [options] [gfile] [lfile]

DESCRIPTION
       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).

OPTIONS
       -h     Display some help.

       -V     Display program version and copyright.

EXAMPLE
       Test the consistency of graph brol.grf:

           $ gtst brol.grf
