+fingerprint is represented by an object of S4 class 'fingerprint' which is
+internally represented a vector of integers, such that each element represents
+the position in the fingerprint that is set to 1.  The bitwise logical
+functions in R are overridden so that they can be used directly with
+'fingerprint' objects.  A number of distance metrics are also available (many
+contributed by Michael Fadock).  Fingerprints can be converted to Euclidean
+vectors (i.e., points on the unit hypersphere) and can also be folded using
+OR.  Arbitrary fingerprint formats can be handled via line handlers.
+Currently handlers are provided for CDK, MOE and BCI fingerprint data.")
