+ * hash - routines for hashing bytes
+ *
+ * When creating a hash table it's important to have a hash function
+ * which mixes well and is fast.  This package supplies such functions.
+ *
+ * The hash functions come in two flavors: the normal ones and the
+ * stable ones.  The normal ones can vary from machine-to-machine and
+ * may change if we find better or faster hash algorithms in future.
+ * The stable ones will always give the same results on any computer,
+ * and on any version of this package.
