These are SCons build tools for Coffeescript files.

In normal use, the Coffeescript.py file would go into ./site_scons/site_tools/, and an SConstruct file would be placed in the project root that sets up a build.

SConstruct::

import os

env = DefaultEnvironment(
        tools = ['Coffeescript'],
        ENV = dict(
            PATH = os.environ['PATH'],
            )
        )

env.SConscript(dirs=['js'], exports=['env'])

js/SConscript::

Import('env')

coffee_files = env.Glob('*.coffee')

js_files = env.Coffeescript(coffee_files)
