   Flags:
       -c
           Cover values extracted from the category labels of the cover map

       -r
           Create reclass map with statistics as category labels

       --overwrite
           Allow output files to overwrite existing files

       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       base=name [required]
           Name of base raster map

       cover=name [required]
           Name of cover raster map

       method=string [required]
           Method of object-based statistic
           Options:  count,  sum,  min,  max, range, average, avedev, variance, stddev, skewness,
           kurtosis, variance2, stddev2, skewness2, kurtosis2
           count: Count of values in specified objects
           sum: Sum of values in specified objects
           min: Minimum of values in specified objects
           max: Maximum of values in specified objects
           range: Range of values (max - min) in specified objects
           average: Average of values in specified objects
           avedev: Average deviation of values in specified objects
           variance: Variance of values in specified objects
           stddev: Standard deviation of values in specified objects
           skewness: Skewness of values in specified objects
           kurtosis: Kurtosis of values in specified objects
           variance2: (2-pass) Variance of values in specified objects
           stddev2: (2-pass) Standard deviation of values in specified objects
           skewness2: (2-pass) Skewness of values in specified objects
           kurtosis2: (2-pass) Kurtosis of values in specified objects

       output=name [required]
           Resultant raster map

DESCRIPTION

       r.stats.zonal is intended to be a partial replacement for r.statistics, with  support  for
       floating-point cover maps at the expense of not support quantiles.
