+#| "This function allows the introduction of new severity classes which can "
+#| "be addressed by the I<severity> argument of the B<fmtmsg>(3) function. "
+#| "By default that latter function only knows how to print messages for "
+#| "severity 0-4 (with strings (none), HALT, ERROR, WARNING, INFO). This "
+#| "call attaches the given string I<s> to the given value I<severity>. If "
+#| "I<s> is NULL, the severity class with the numeric value I<severity> is "
+#| "removed. It is not possible to overwrite or remove one of the default "
+#| "severity classes. The severity value must be nonnegative."
