+\begin{ccPkgDescription}{2D Snap Rounding}
+\ccPkgSummary{
+Snap Rounding is a well known method for converting
+arbitrary-precision arrangements of segments into a fixed-precision
+representation. In the study of robust geometric computing, it can be
+classified as a finite precision approximation technique. Iterated
+Snap Rounding is a modification of Snap Rounding in which each vertex
+is at least half-the-width-of-a-pixel away from any non-incident
+edge. This package supports both methods.}
