bcomps - biconnected components filter for graphs

       Emden R. Gansner <erg@research.att.com>

       It  is  possible,  though  unlikely, that the names used for connected components and their subgraphs may
       conflict with existing subgraph names.

bcomps decomposes graphs into their biconnected components, printing the components to standard output.

       The following operand is supported:

       files   Names  of files containing 1 or more graphs in dot format.  If no files operand is specified, the
               standard input will be used.

       The following options are supported:

       -s     No output graph is printed. Implies the -v flag.

       -t     Print the underlying block-cutvertex tree.

       -x     Each biconnected component is printed as a separate root graph.

       -v     Prints number of blocks and cutvertices.

       -ooutfile
              If  specified,  each  root  graph  will be written to a different file with the names derived from
              outfile. In particular, if both -o and -x flags  are  used,  then  each  block  is  written  to  a
              different  file.  If  outfile does not have a suffix, the nth block of the ith graph is written to
              outfile_n_i. However, the 0th block of the 0th graph is written to outfile.

              If outfile has a suffix, i.e., has the form base.sfx, then the files will have the  same  name  as
              above, except appended with .sfx.

              The  block-cutvertex  tree  of  ith  graph  is  written to outfile_n_T, with an appended suffix if
              specified.

       By default, each input graph  is  printed,  with  each  block  given  as  a  subgraph  whose  name  is  a
       concatenation of the name of the input graph, the string "_bcc_" and the number of the block.

bcomps returns 0 if all the input graphs are biconnected; and non-zero if any graph has multiple  blocks,
       or any error occurred.
