[FWTools] contours as polygons

I use gdal_contour to create contours as lines.  Does anyone know of a 
similar tool or have some code that will create polygons instead of 
lines when contouring a surface?  Each polygon would represent the area 
between n1 and n2.  I have the ConRec code and thought about writing 
this myself, but it gets complicated with donut polygons.  I bet 
someone's done this before.  Maybe there's a better mailing list for 
this question?  Thanks.
