+     "This package provides functions to manipulate binary fingerprints of
+arbitrary length.  A fingerprint is represented by an object of S4 class
+@code{fingerprint}.  The bitwise logical functions in R are overridden so that
+they can be used directly with @code{fingerprint} objects.  A number of
+distance metrics are also available.  Fingerprints can be converted to
+Euclidean vectors (i.e., points on the unit hypersphere) and can also be
+folded.  Arbitrary fingerprint formats can be handled via line handlers.
+Currently handlers are provided for CDK, MOE and BCI fingerprint data.")
