Initial value:

(INFO
 ". Only works on 1, 2, or 3 dimensions.  The window "
 "over which filtering is done is always square, and "
 "only a simplistic weighting scheme is available. "
 "The method is cheap because it does the median "
 "or mode based on a histogram, which enforces a quantization to the number "
 "of bins in the histogram, which probably means a loss of precision for "
 "anything except 8-bit data.  Also, integral values can be recovered "
 "exactly only when the number of bins is exactly min-max+1 (as reported "
 "by \"unu minmax\"). ")
