+/**
+ * Skein interface. The Skein specification defines three main
+ * functions, called Skein-256, Skein-512 and Skein-1024, which can be
+ * further parameterized with an output length. For the SHA-3
+ * competition, Skein-512 is used for output sizes of 224, 256, 384 and
+ * 512 bits; this is what this code implements. Thus, we hereafter call
+ * Skein-224, Skein-256, Skein-384 and Skein-512 what the Skein
+ * specification defines as Skein-512-224, Skein-512-256, Skein-512-384
+ * and Skein-512-512, respectively.
