DESCRIPTION

       The gnmanalyse program provides analysing capabilities of geographical networks in GDAL.
       The results of calculations are return in an OGRLayer format or as a console text output
       if such layer is undefined. All calculations are made considering the blocking state of
       features.

       dijkstra start_gfid end_gfid:
           Calculates the best path between two points using Dijkstra algorithm from start_gfid
           point to end_gfid point.

       kpaths start_gfid end_gfid:
           Calculates K shortest paths between two points using Yen's algorithm (which internally
           uses Dijkstra algorithm for single path calculating) from start_gfid point to end_gfid
           point.

       resource:
           Calculates the 'resource distribution'. The connected components search is performed
           using breadth-first search and starting from that features which are marked by rules
           as 'EMITTERS'.

       -ds ds_name:
           The name&path of the dataset to save the layer with resulting paths. Not need to be
           existed dataset.

       -f ds_format:
           Define this to set the format of newly created dataset.

       -l layer_name:
           The name of the resulting layer. If the layer exist already - it will be rewritten.

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

       -dsco NAME=VALUE:
           Dataset creation option (format specific)

       -lco NAME=VALUE:
           Layer creation option (format specific)

       -alo NAME=VALUE:
           Algorithm option (format specific)
