+=head1 Warning and Dieing
+
+In all these calls, the C<U32 wI<n>> parameters are warning category
+constants. You can see the ones currently available in
+L<warnings/Category Hierarchy>, just capitalize all letters in the names
+and prefix them by C<WARN_>. So, for example, the category C<void> used in a
+perl program becomes C<WARN_VOID> when used in XS code and passed to one of
+the calls below.

+=for apidoc_item ||ckWARN4|U32 w1|U32 w2|U32 w3|U32 w4
+These return a boolean as to whether or not warnings are enabled for any of
+the warning category(ies) parameters: C<w>, C<w1>, ....
+
+Should any of the categories by default be enabled even if not within the
+scope of S<C<use warnings>>, instead use the C<L</ckWARN_d>> macros.
+
+The categories must be completely independent, one may not be subclassed from
+the other.

+These macros are used to pack warning categories into a single U32 to pass to
+macros and functions that take a warning category parameter. The number of
+categories to pack is given by the name, with a corresponding number of
+category parameters passed.
