hem, forgotten implementation, fixed in the attachment...

Can I define multiple MIB files with multiple arguments?

this is simply a wrapper around the 'snmpcmd' (i.e works for snmp{walk,get,
...}) "-M DIRLIST"

I've modified the option for:
-m DIRLIST -- colon separated list of directories to also search for MIBs

the specified DIRLIST is appended to Net SNMP DIRLIST

as told previously, it won't work out of the box!
the mapping (1rst column in the .c file, prefixed with "unmapped...") has
to be edited to use actual NUT variables name, and possibly value lookup.
there is a small example in the .c file.

that said, I'm still interested in the test results of mode 1

with the sysOID support, specifying "mibs" is not that useful anymore.
