They don't accept a parameter. I can rectify that, I guess sometimes
you'd like that (especially for big jobs). The log should contain
entries from both, with a direction field.

Let me double check tonight and make sure it doesn't truncate the log or
anything like that, I don't think I've ever used the log like this. It
should just append.
