SNMP Walk standalone

Is there any way to use the SNMPWalk tool built into the Dude as a standalone program, or is there another program out there with the same functionality? I can’t find anything as good as the built-in one, but we are moving away from the Dude as a monitoring platform.

http://www.paessler.com/tools/snmptester is a tool I quite often use to debug snmp (free as well)
