Passing a '\-' as either argument, explicitly specifies to read the input from standard input and write the output to standard output, respectively. .PP The input graph type will be determined automatically. If the output graph is given as a filename, then the output type will be GraphML if the filename ends with .xml and dot if the filename ends with .dot. If the output is done on standard output then it will happen in the same format as the input graph. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-h, \-\-help\fR" 4 .IX Item "-h, --help" Display help. .IP "\fB\-\-target=\fR\fI\s-1TARGET\s0\fR" 4 .IX Item "--target=TARGET" This option picks the target vertex of which the ancestors are computed. The \&\s-1TARGET\s0 argument is a key/value pair (separated by a colon) of a graph attribute and its desired value. If more than one vertex matches the given key/value pair, then the smallest (by node comparison) is chosen. .Sp The special key \f(CW\*(C`_\|_ID_\|_\*(C'\fR allows one to select the unique vertex identifier. .Sp This option can be specified more than once. The final set of vertices is chosen such that all vertices match all key/value pairs.
