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.

       --help Show this help message and exit

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

       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'.

       -d <ds_name>
              The name and 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)
