The following files were created:
  snmpd.conf  
These files should be moved to /usr/local/share/snmp if you
want them used by everyone on the system.  In the future, if you add 
the -i option to the command line I'll copy them there automatically for you.
Or, if you want them for your personal use only, copy them to
/root/.snmp .  In the future, if you add the -p option to the
command line I'll copy them there automatically for you.
