[Obo-owltools] Example error

[Kim R. <km...@ca...>]

Hi.

I'm trying the examples from:
  https://code.google.com/p/owltools/wiki/CommandLineExamples

I just tried:
  owltools cl.obo pro.obo go.obo --merge-support-ontologies --to owl -o cl-merged.owl

but got:
  could not parse:--to Exception:java.io.FileNotFoundException: --to (No such file or directory)

Has the argument parsing changed?

Thanks,
Kim.
