+/* This API is incredibly limited and unsophisticated.  objc_error()
+   generally causes the program to abort, so it should only be used
+   when something so dramatic happens that it could be pointless to
+   continue.  Only two cases I can think of: failure to allocate new
+   memory or failure to load an Objective-C module.
+*/
+/* Error handling
+  
+   Call objc_error() or objc_verror() to record an error; this error
+   routine will generally exit the program but not necessarily if the
+   user has installed his own error handler.
+  
+   Call objc_set_error_handler to assign your own function for
+   handling errors.  The function should return YES if it is ok
+   to continue execution, or return NO or just abort if the
+   program should be stopped.  The default error handler is just to
+   print a message on stderr.
+  
+   The error handler function should be of type objc_error_handler
+   The first parameter is an object instance of relevance.
+   The second parameter is an error code.
+   The third parameter is a format string in the printf style.
+   The fourth parameter is a variable list of arguments.  */
