+/* var.c - a typeless variable class
+ *
+ * This class is used to represent variable values, which may have any type.
+ * Among others, it will be used inside rsyslog's expression system, but
+ * also internally at any place where a typeless variable is needed.
+ *
+ * Module begun 2008-02-20 by Rainer Gerhards, with some code taken
+ * from the obj.c/.h files.
+ *
+ * Copyright 2007-2016 Rainer Gerhards and Adiscon GmbH.
