I think you suggested using the args package, not me.

As far as I know, the args package insists that options comes before arguments.
This is not flexible enough for dart2js, and I think I heard Johnni express the
same concern for dartdoc. However, Bob and Johnni should make the call, not me.

Once you've updated the CL cf. the comment, I'll commit it for you.

Added reference to find-as-you-type search box in help for static file
generation mode.

Done.

[butlermatt, 2012-09-17 17:00:35]

One small additional patch to include a missing command invocation in help.

[Bob Nystrom, 2012-09-17 22:57:13]

LGTM!

Peter, I generally think mixing options and non-option args is asking for
trouble given that some options may or may not take values:

$ somecommand --foo bar --baz blah

Is "bar" the value for the option --foo, or is --foo a boolean flag and bar is
just a regular argument? Args can determine that, but it's still
context-sensitive parsing which makes me feel icky. If it's really important to
you, though, it would be pretty easy to make args support it.

If it looks good to you now, can you commit this for me?
Thanks,
