TODO: maybe this should run "frogc"?

What's frogc? Add this as a TODO?

I think the idea is it's another entry point that doesn't need --compile-only.
It'll eventually replace frog.py.

But I just noticed you're using frogsh, so nevermind :)

a more compact way to write the 2 lines above:

frog = os.path.abspath(utils.GetDartRunner(self.mode, self.arch, 'frogsh'))

+    cmd = [frog, '--compile-only', '--out=%s' % self.GetScriptPath()]

[Siggi Cherem (dart-lang), 2011/11/11 00:06:02]

you might need to pass --libdir here

[Emily Fortuna, 2011/11/11 00:58:41]

Done.
