Is there documentation specifying what functionality is required from the QC

  At present, the ffTK plugin only supports Gaussian. As you can most
likely guess, support for other QM packages is a highly requested future
development, but it requires that comparable features are available in the
other QM tool. GAMESS lacks the required functionality at present.
My understanding is that ORCA developers were/are planning to develop the
required functionality, but I don't have an current status update there at
this time. Perhaps Chris or JC might comment further.
