This is interesting, I haven't go that far in the API but you can still do something like: CLI.enumerate(Seq("curl", "-s", "http://news.ycombinator.com/")

This is interesting, I haven't go that far in the API but you can still do something like: CLI.enumerate(Seq("curl", "-s", "http://news.ycombinator.com/")) and val curl = (url: String) => CLI.enumerate(Seq("curl", "-s", url)) This Seq synthax is provided by scala.sys.process, AFAIK, as a nice side-effect, it guarantees some safety of command parameters (avoiding injections).
