		    <gnm_name> [<layer>	[<layer>]...]

DESCRIPTION
       The  gnmmanage  program can perform various managing operations on geo-
       graphical networks in GDAL. In addition to creating and	deleting  net-
       works this includes capabilities	of managing network's features,	topol-
       ogy and rules.

       --help Show this	help message and exit

       --help-general
	      Gives a brief usage message for the generic GDAL commandline op-
	      tions and	exit.

       -info  Different	 information  about  network: system and class layers,
	      network metadata,	network	spatial	reference.

       create Create network.

	      -f <format_name>
		     Output file format	name.

	      -t_srs <srs_name>
		     Spatial reference input.

	      -dsco <NAME>=<VALUE>
		     Network creation option set as pair name=value.

       import <src_dataset_name>
	      Import layer with	dataset	name to	copy.

	      -l <layer_name>
		     Layer name	in dataset. If unset, 0	layer is copied.

       connect <gfid_src> <gfid_tgt> <gfid_con>
	      Make a topological connection, where the gfid_src	 and  gfid_tgt
	      are  vertices  and  gfid_con is edge (gfid_con can be -1,	so the
	      system edge will be inserted).

	      Manually assign the following values:

	      -c <cost>
		     Cost / weight

	      -ic <invcost>
		     Inverse cost

	      -dir <dir>
		     Direction of the edge.

       disconnect <gfid_src> <gfid_tgt>	<gfid_con>
	      Removes the connection from the graph.

       rule <rule_str>
	      Creates a	rule in	the network by the given rule_str string.

       autoconnect <tolerance>
	      Create topology automatically with the  given  double  tolerance
	      and layer	names. In no layer name	provided all layers of network
	      will be used.

       delete Delete network.

       change Change blocking state of network edges or	vertices.

	      -bl <gfid>
		     Block  feature  before  the main operation. Blocking fea-
		     tures are saved in	the special layer.

	      -unbl <gfid>
		     Unblock feature before the	main operation.

	      -unblall
		     Unblock all blocked features before the main operation.

       <gnm_name>
	      The network to work with (path and name).

       <layer>
	      The network layer	name.
