-# This is a first stab at creating a Firefox extension which can run Dart
-# code by using frog's in-browser compilation. This is a minimal attempt,
-# with a UI that needs a total gutting, but it gets things start in Firefox.
-# Over time, I hope that Dart in FF becomes a really nice development path.
-
-# This script first calls copy_libs.py to get the libs staged correctly.
