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 re-
       sulting 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 com-
       pressed file extension, such as in 'brol.grf.bz2' or '-.gz'.  The  com-
       pression	 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
