- --help
- Print usage summary
- --verbose
- Verbose module output
- --quiet

Parameters:
- input=string[,string,...] [required]
- Raster map(s) to be quantized
- rules=name
- Path to rules file ("-" to read from stdin)
- basemap=string
- Base map to take quant rules from
- fprange=dmin,dmax
- Floating point range: dmin,dmax
- range=min,max
- Integer range: min,max
 
r.quant produces the quantization file for a floating-point map.
The map parameter defines the map for which the rules are to be
created. If more than one map is specified, then this implies that the
floating-point range is the minimum and maximum of all the maps together,
unless either basemap=map or fprange=min,max is specified.
The quant rules have to be entered interactively.
If rules is specified, the input has the form:
value1:value2:cat1:[cat2]
where value1 and value2 are floating point values and
cat1 and cat2 are integers. If cat2 is missing,
it is taken to be equal to cat1. All values
can be "*" which means infinity.
It is an error to specify both 
basemap and 
fprange.
