Does not support "AUGMENTS"?

[Ed Wildgoose]

I think the current library fails if using "AUGMENTS" in an mib? I wanted to implement IF-MIB in my app, so I created a stub something like:

defmodule SnmpAgent.Mib.If do
  use Snmp.Mib, name: "IF-MIB"
end

Then added IF-MIB and IANAifType-MIB into my local mibs directory. This fails with an error:

Generated sys_data app

If I replace the "AUGMENTS { ifEntry }" in IfXEntry, then it compiles (and gives me errors about missing definitions)

So I speculate that it's something to do with the thing being augmented being described in the same file? However, I'm not sure how to progress to resolve this? Any guidance?
