#define DESCRIPTION "\
Notes:\n\
- This plugin requres that the MRTGEXT.NLM file from James Drews' MRTG\n\
extension for NetWare be loaded on the Novell servers you wish to check.\n\
(available from http://www.engr.wisc.edu/~drews/mrtg/)\n\
- Values for critical thresholds should be lower than warning thresholds\n\
when the following variables are checked: VPF, VKF, LTCH, CBUFF, DCB, \n\
TCB, LRUS and LRUM.\n"
