+%description
+The "z" library implements the commonly required image processing basics of
+scaling, color space conversion, and depth conversion. A simple API enables
+conversion between any supported formats to operate with minimal knowledge from
+the programmer. All library routines were designed from the ground-up with
+correctness, flexibility, and thread-safety as first priorities. Allocation,
+buffering, and I/O are cleanly separated from processing, allowing the
+programmer to adapt "z" to many scenarios.
