+SNMPv2c TRAP via Twisted inline callbacks
++++++++++++++++++++++++++++++++++++++++++
+
+Send SNMPv2c TRAP through unified SNMPv3 message processing framework
+using the following options:
+
+* SNMPv2c
+* with community name 'public'
+* over IPv4/UDP
+* send TRAP notification
+* with Generic Trap #1 (warmStart) and Specific Trap 0
+* include managed object information '1.3.6.1.2.1.1.1.0' = 'my system'
+
+Functionally similar to:
+
+| $ snmptrap -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2 1.3.6.1.2.1.1.1.0 s "Hello from Twisted"
