+/**************************************************************************
+**
+** Interface declarations and internal definitions for Skein hashing.
+**
+** Source code author: Doug Whiting, 2008.
+**
+** This algorithm and source code is released to the public domain.
+**
+***************************************************************************
+** 
+** The following compile-time switches may be defined to control some
+** tradeoffs between speed, code size, error checking, and security.
+**
+** The "default" note explains what happens when the switch is not defined.
+**
+**  SKEIN_DEBUG            -- make callouts from inside Skein code
+**                            to examine/display intermediate values.
+**                            [default: no callouts (no overhead)]
+**
+**  SKEIN_ERR_CHECK        -- how error checking is handled inside Skein
+**                            code. If not defined, most error checking 
+**                            is disabled (for performance). Otherwise, 
+**                            the switch value is interpreted as:
+**                                0: use assert()      to flag errors
+**                                1: return SKEIN_FAIL to flag errors
