time will grow exponentially with the distance between contour lines.
-<h2>BUGS</h2>
-
-<em>r.surf.contour</em> has not been fully updated for NULL support and still
-considers a value of "<tt>0</tt>" to be NULL. Thus any contour lines at 0
-elevation (e.g. the coastline) will be ignored. In such cases converting any
-0 values in the input map to -1 with <em>r.mapcalc</em> may be a suitable
-work-around.
-<p>
-Currently <em>r.surf.contour</em> will only produce CELL (integer) map output.
-If you would like a finer grade output map (i.e. floating point) it is
-recommended to multiply the <b>input</b> map by 1000 (for example) using
-<em>r.mapcalc</em>, then divide the resultant <em>r.surf.contour</em>
-<b>output</b> map by 1000.0, again with <em>r.mapcalc</em>.

-Volunteers are sought to remedy both these issues.
