+ * NAME
+ *
+ *    #define SILC_VERIFY(experssion)
+ *
+ * DESCRIPTION
+ *
+ *    Verification macro that prints error message to stderr and calls
+ *    abort() if the `expression' is false (ie. compares equal to zero)
+ *    on debug builds (SILC_DEBUG defined), and prints error message to
+ *    stderr on release builds (SILC_DEBUG undefined) but does not abort().
+ *    This macro is always compiled even if debugging (SILC_DEBUG) is not
+ *    defined.
