quartile, median, third quartile, and maximum.
.SH OPTIONS
.SH Flags:
.VL 4m
.LI "\*L-a\*O 
Use all sites found in the named sites file, rather than
limiting output to sites falling within the current geographic region.
.LI "\*L-g\*O 
Print the statistics in shell script style (similar to g.region).
.LI "\*L-l\*O 
Use site descriptions (category labels) for z values.
Sites must be in the (E|N|#n desc) format for this to work.
Default format is just three pipe-separated floating point
numbers (E|N|desc).
.LI "\*L-q\*O 
Quiet. Cut out the chatter.
.LE
.SH Parameters:
.VL 4m
.LI "\*Lsites=\*Oname

.SH BUGS

records (requires a lot of memory).
