+class RFastdigest(RPackage):
+    """Fast, Low Memory-Footprint Digests of R Objects
+
+    Provides an R interface to Bob Jenkin's streaming, non-cryptographic
+    'SpookyHash' hash algorithm for use in digest-based comparisons of R
+    objects. 'fastdigest' plugs directly into R's internal serialization
+    machinery, allowing digests of all R objects the serialize() function
+    supports, including reference-style objects via custom hooks. Speed is
+    high and scales linearly by object size;
+    memory usage is constant and negligible."""
