}
complete -F _crew crew

Thanks for adding that.

Hey @cstrouse: I really like this idea, however, I was unable to get the script working. I have executable compgen, pcregrep and complete commands available. If I type crew in<tab>, it won't complete with crew install. Is there something I might be missing?
Thanks

@uberhacker I think it only completes package names in the current state.
