NAME
     cluster  -  find  clusters  in a graph and augment the graph
     with this information.

SYNOPSIS
     cluster [-v?]  [ -Ck ] [ -o outfile ] [ files ]

DESCRIPTION
     cluster takes as input a graph in  DOT  format,  finds  node
     clusters  and augments the graph with this information.  The
     clusters are specified by the "cluster"  attribute  attached
     to nodes; cluster values are non-negative integers.  cluster
     attempts to maximize the modularity of the  clustering.   If
     the edge attribute "weight" is defined, this will be used in
     computing the clustering.

OPTIONS
     The following options are supported:

     -Ck  specifies a targeted number of clusters that should  be
          generated.  The specified number k is only a suggestion
          and may not be realisable.  If k == 0, the default, the
          number  of  clusters  that  approximately optimizes the
          modularity is returned.

     -ooutfile
          Specifies that output should go into the file  outfile.
          By default, stdout is used.

     -v   Verbose mode.

EXAMPLES
     Applying cluster to the following graph,

        graph {
            1--2 [weight=10.]
            2--3 [weight=1]
            3--4 [weight=10.]
            4--5 [weight=10]
            5--6 [weight=10]
            3--6 [weight=0.1]
            4--6 [weight=10.]
           }

     gives

        graph {
              node [cluster="-1"];
              1 [cluster=1];
              2 [cluster=1];
              3 [cluster=2];
              4 [cluster=2];
