NAME

       botch-graph-neighborhood - extract the neighborhood around a vertex

SYNOPSIS

       botch-graph-neighborhood [options] --center CENTER [--center CENTER ...] [ingraph]
       [outgraph]

DESCRIPTION

       Extract the neighborhood around a center vertex of a graph in GraphML or dot format.

       The --center option is mandatory and can be specified more than once.

       If either (or both) of the positional arguments is/are omitted, then read GraphML or dot
       from standard input and/or write GraphML or dot to standard output, respectively.  Passing
       a '-' as either argument, explicitly specifies to read the input from standard input and
       write the output to standard output, respectively.

       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.

OPTIONS

       -h, --help
           Display help.

       --depth=DEPTH
           range of neighborhood to extract (Default: 1)

       --center=CENTER
           This option picks the center vertex of which the neighborhood is computed. The CENTER
           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.

           The special key "__ID__" allows one to select the unique vertex identifier.

           This option can be specified more than once. The final set of vertices is chosen such
           that all vertices match all key/value pairs. Multiple --center options thus form a
           logical conjunction (they are AND-ed together).

       -v, --verbose
           Be verbose.
