SYNOPSIS

       biplabg [-q] [infile [outfile]]

DESCRIPTION

              Label bipartite graphs so that the colour classes are contiguous.

              The  first vertex of each component is assigned the first colour.  Vertices in each
              colour class have the same relative order  as  before.   Non-bipartite  graphs  are
              rejected.

              The output file has a header if and only if the input file does.

       -q     Suppress auxiliary information.
