NAME
       bcomps - biconnected components filter for graphs

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

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

OPTIONS
       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 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.

OPERANDS
       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.

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

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