+/* SEVERITY GUIDELINES:
+ *
+ * ERR_STOP: Something so bad has happened that the whole service must
+ * stop. Something like a malloc() error or similar magnitude
+ * error.
+ *
+ * ERR_FATAL: Something so bad has happened that the module cannot usefully
+ * function any more, but won't necessarily prevent other modules
+ * from working.
+ *
+ * ERR_ERROR: Something is wrong, perhaps a data structure is inconsistent
+ * or something similar has gone wrong internally. This might
+ * indicate a larger problem but the module can continue working
+ * for now.
+ *
+ * ERR_WARNING: Something slightly out of the ordinary has happened (e.g.
+ * the IRCD sent a bogus message). The module can continue
+ * working though without serious harm.
+ *
+ * ERR_INFO: Not an error condition. Something noteworthy has happened,
+ * like a major module has started up. These will typically be
+ * seen all the time on most setups so try not to be too spammy.
+ *
+ * ERR_DEBUG: Not an error condition. Something less significant has
+ * happened which might be of interest if someone is attempting
+ * to debug a problem. Nevertheless try not to be too spammy.
