+=head1 DESCRIPTION
+
+To the new policies for API methods are: if there's an error message to the user, there's one to the log. 
+Only trap exceptions in C<www_> methods and always report them.
+
+API methods now have a policy of throwing errors from this class to be caught by C<eval { }>
+or C<catch { }> in the calling code.
+Code using the API (such as in C<www_> methods, upgrade scripts, and so forth) should 
+use C<Exception::Class> to identify it, then either handle it gracefully or else 
+propogate it.
