       bcomps - biconnected components filter for graphs

       bcomps [ -stvx?	] [ -ooutfile ] [ files ]

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

       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.

       -o outfile
	      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  dif‐
	      ferent 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

	      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.

       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.

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

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