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 dif-
ferent 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 stan-
dard 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.
