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)
