/*********************************************************************
* GRASS program to create a raster map with non-zero data
* in random locations.
* Locations will be within non-zero data in the input layer.
* (unless -z option specified)
* If it necessary to restrict the locations to only some categories
* of the input map, a reclass map should be constructed first
* and used as input to this program.
*
* Number of random cells can be a fixed number or a percentage of cells.
*
* Resulting raster map consists of original cell values at the selected
* random locations and zero elsewhere.
*
* A sitefile may optionally be created.
*
* Usage:
* r.random [-iqz] input=name [raster_output=name] [sites_output=name] n=n[%]
*
* -i mean report number of total cells and null cells
* -q means run quietly
* -z means generate random locations for zero-data as well
*
