SNMP MIB and SNMPTT helper script for Zabbix integration

# This Script creates the following files to be used for
# Zabbix SNMP and SNMP trap integration:
#
# /etc/snmp/snmp.conf
# /etc/snmp/snmptt.conf.VENDOR
# Symlink vendor specific MIB files from
#  $MIBS_VENDORS to $MIBS
#
# The actual order for the snmp.conf is defined in a vendor
# specific file that needs to be created manually!
#
