+/* prop.c - rsyslog's prop object
+ *
+ * This object is meant to support message properties that are stored
+ * seperately from the message. The main intent is to support properties
+ * that are "constant" during a period of time, so that many messages may
+ * contain a reference to the same property. It is important, though, that
+ * properties are destroyed when they are no longer needed.
+ *
+ * Please note that this is a performance-critical part of the software and
+ * as such we may use some methods in here which do not look elegant, but
+ * which are fast...
