+/* omsnmp.c
+ *
+ * This module sends an snmp trap. More text will come here soon ^^
+ *
+ * This module will become part of the CVS and the rsyslog project because I think
+ * it is a generally useful debugging, testing and development aid for everyone
+ * involved with rsyslog.
+ *
+ * CURRENT SUPPORTED COMMANDS:
+ *
+ * :omsnmp:sleep <seconds> <milliseconds>
+ *
+ * Must be specified exactly as above. Keep in mind milliseconds are a millionth
+ * of a second!
+ *
+ * NOTE: read comments in module-template.h to understand how this file
+ *       works!
