To be honest, I missed that one.  A cursory glance seems to indicate
that one must statically configure all of the agents that might be
queried ahead of time in a local configuration file.

I'm searching for a simple client API that would be equivalent to
using net-snmp's 'snmpget' command-line utility?  Ideally, such an API
call would take a hostname, community, and oid as arguments, and then
return the result.

If such an interface does not exist, would it be easy for me to
implement using the existing code?  Or should I simply resort to
calling out to the OS to invoke the command-line 'snmpget'?  

And finally, does the Erlang SNMP library support the placing of SNMP
GETBULK requests?  This is important in my case as I need to query
some large tables on my Cisco routers.

Thanks,
Pete
