NAME
       gbase - sets the base value of a source graph

SYNOPSIS
       gbase [options] bval [igfile] [ogfile]

DESCRIPTION
       The gbase program allows one to set to bval the base value of a source
       graph, that is, the starting index used to number its vertices and
       edges. The base value can be set to 0 or 1, so that graphs can be
       easily imported from and/or exported to tools written in C or Fortran.
       Scotch can handle graphs irrespective of their base value.

       When the proper libraries have been included at compile time, gbase 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
       Set the base of graph 'brol.grf' to 1, and write the modified graph to
       file 'brol_b1.grf'.

           $ gbase 1 brol.grf brol_b1.grf
