Interesting. It's failing the travis builds in the check phase though. It's giving:

checking whether the package can be loaded with stated dependencies ... WARNING
Error : .onAttach failed in attachNamespace() for 'docstring', details:
  call: get("?", parent.env(parent.env(.GlobalEnv)))
  error: object '?' not found
Error: package or namespace load failed for ‘docstring’
Execution halted

Fixed by changing get to get0.

I've been quite busy lately and haven't had much time to play around with this. I'll give it some attention hopefully in the next week or so.
