+ (description
+ "The drizzle library is a Python package for combining dithered images into
+a single image. This library is derived from code used in DrizzlePac. Like
+DrizzlePac, most of the code is implemented in the C language. The biggest
+change from DrizzlePac is that this code passes an array that maps the input to
+output image into the C code, while the DrizzlePac code computes the mapping by
+using a Python callback. Switching to using an array allowed the code to be
+greatly simplified.")
