So, at the moment, I don't know what a "discriminatively trained" tagger
is and wouldn't know how to start trying to answer such a question...

But hopefully I won't have to, because I was actually just saying
something incredibly simple and non-technical, that the brillig
executable could just provide a thin wrapper around different kinds of
taggers (as alternatives to each other, completely disjoint).
You know, files go in, tags come out... but this was before I looked
at the training file format and understood that this is what sequor
provides.  Oh well, this probably makes brillig just a bit redundant in
infrastructure terms. :-)

PS. can we have a small release with '-rtsopts'?
