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

DESCRIPTION
     The gnmmanage program can perform various managing operations on geographi-
     cal  networks  in	GDAL. In addition to creating and deleting networks this
     includes capabilities of managing network's features, topology and rules.

     --help
	    Show this help message and exit

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

     -info  Different information about network: system and class  layers,  net-
	    work 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	features
		   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.

RETURN STATUS CODE
     The  program returns status code 0 in case of success, and non-zero in case
     of error (non-blocking errors emitted as warnings are considered as a  suc-
     cessful execution).
