+ * DESCRIPTION
+ * `cf_register' is called by plugins that wish to receive config keys. The
+ * plugin will then receive all keys it registered for if they're found in a
+ * `<Plugin $type>' section.
+ *
+ * PARAMETERS
+ * `type' Name of the plugin (must be the same as passed to
+ * `plugin_register'
+ * `callback' Pointer to the callback function. The callback must return zero
+ * upon success, a value smaller than zero if it doesn't know how
+ * to handle the `key' passed to it (the first argument) or a
+ * value greater than zero if it knows how to handle the key but
+ * failed.
+ * `keys' Array of key values this plugin wished to receive. The last
+ * element must be a NULL-pointer.
+ * `keys_num' Number of elements in the array (not counting the last NULL-
+ * pointer.
+ *
+ * NOTES
+ * `cf_unregister' will be called for `type' to make sure only one record
+ * exists for each `type' at any time. This means that `cf_register' may be
+ * called multiple times, but only the last call will have an effect.

+ * DESCRIPTION

+ *
+ * PARAMETERS
+ * `filename' An additional filename to look for. This function calls
+ * `lc_process' which already searches many standard locations..
+ * If set to NULL will use the `CONFIGFILE' define.
+ *
+ * RETURN VALUE
+ * Returns zero upon success and non-zero otherwise. A error-message will have
+ * been printed in this case.
