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
