-@BeginDescription
-This operator distributes a dataset into smaller pieces. Each output file contains a different region of the horizontal 
-source grid. A target grid region contains a regular longitude/latitude box of the source grid. Only rectilinear source 
-grids are supported by this operator. The number of different regions can be specified with the parameter @var{nx} and @var{ny}.
-The output files will be named <obase><xxx><suffix> where suffix is the filename extension derived from the file format. 
-xxx will have five digits with the number of the target region.

-@BeginParameter nx
-@Item = nx
-INTEGER  Number of regions in x direction
-@Item = ny
-INTEGER  Number of regions in y direction [default: 1]

-@BeginNote
-This operator needs to open all output files simultaneously.
-The maximum number of open files depends on the operating system!

-@BeginExample
-Distribute a file into 6 smaller files, each output file receives one half of x and a third of y of the source grid:
-@BeginVerbatim
-   cdo distgrid,2,3 ifile.nc obase
-@EndVerbatim

-Below is a schematic illustration of the example:
