It's a perl script - so
less `which mib2c`
should work :-)

The MIB module registration calls take an OID array,
but you're perfectly at liberty to use "read_objid" to generate this OID.
The advantage of hardcoding the numeric OID into the initialisation code,
is that the agent is then not dependent on the MIB files being available
(as well as being slightly more efficient). A small increase in work for the
coder makes a noticeable difference to the reliability of the agent.
But if you prefer to explicitly convert names into OIDs, then feel free.

Remember that mib2c is simply a tool to help generate code.
If you're happy writing equivalent code by hand, then there's
nothing to stop you doing so.
(That's actually how I tend to work, most of the time).
You can still use numeric OIDs in your registration code, even
if you haven't used mib2c to generate the code.
