R: do random access to OID labels
u: top-level OIDs must have '.' prefix (UCD-style)
s SUFFIX: Append all textual OIDs with SUFFIX before parsing
S PREFIX: Prepend all textual OIDs with PREFIX before parsing
-L LOGOPTS Toggle various defaults controlling logging:
e: log to standard error
o: log to standard output
n: don't log at all
f file: log to the specified file
s facility: log to syslog (via the specified facility)
(variants)
[EON] pri: log to standard error, output or /dev/null for level 'pri' and above
[EON] p1-p2: log to standard error, output or /dev/null for levels 'p1' to 'p2'
[FS] pri token: log to file/syslog for level 'pri' and above
[FS] p1-p2 token: log to file/syslog for levels 'p1' to 'p2'
-C APPOPTS Set various application specific behaviours:
p: print the number of variables found
i: include given OID in the search range
I: don't include the given OID, even if no results are returned
c: do not check returned OIDs are increasing
t: Display wall-clock time to complete the walk
T: Display wall-clock time to complete each request
E {OID}: End the walk at the specified OID
