Sprout is an open-source, cross-platform project generation and configuration tool

Usage: #{File.basename($0)} [options] [ProjectName]

Examples:

Create a new ActionScript 3.0 project named 'SomeProject':
  #{File.basename($0)} -n as3 SomeProject

Create a new ActionScript 2.0 project named 'OtherProject':
  #{File.basename($0)} -n as2 OtherProject

Remove all Sprout gems and cached files:
  #{File.basename($0)} -R

Options are:
