Yes, I think it should have that.  Right now, the code's a bit messy, 
and there's no "engine", just mostly-separe

Fai's not really suitable for scripting at the moment, so while shell 
would make sense, I'm not sure about emacs.

Looks reasonable.  I don't know that I'll have any prefixes, though.

I suppose you might also want to be able to do "complete --source-files" 
 or "complete --command".

Yeah, one way would be:
package-versions [--library] [--full] [--revisions] ARCHIVE

I'd also like to specify the output format at the same time, but maybe 
I'm getting ahead of myself.

Ah.  I'll apply that fix.
