+# GETNEXT Command Generator Application
+#
+# Perform SNMP GETNEXT operation with the following options:
+#
+# * with SNMPv2c, community 'public'
+# * over IPv4/UDP
+# * to an Agent at demo.snmplabs.com:161
+# * for an OID in string form
+# * resolve response OIDs and values into human-freidly form
+# * stop when response OIDs leave the scopes of initial OIDs
+#
+# This script performs similar to the following Net-SNMP command:
+# 
+# $ snmpwalk -v2c -c public demo.snmplabs.com 1.3.6.1.2.1.1
+#
+# The lookupNames and lookupValues keyword arguments will make pysnmp
+# trying to resolve OIDs and values, in response variable-bindings,
+# into human-friendly form. If response OIDs do not belong to any of 
+# currently loaded MIBs, unresolved OIDs and values will still be
+# returned.
