<para>
This function is used to load additional, e.g. vendor specific, MIBs so that
human readable OIDs like <literal>VENDOR-MIB::foo.1</literal> instead of error prone numeric OIDs
can be used.
</para>
<para>
The order in which the MIBs are loaded does matter as the underlying Net-SNMP
library will print warnings if referenced objects cannot be resolved.

The above example is made up but the results would look like:

Array

[FOO-BAR-MIB::someTable.0] => Gauge32: 6
