Sure. I'll post the commands along with the output I posted before.
Note that `Environment` is a fundamental function that gets called in
just about every SConstruct file.

---BEGIN---
$ mkdir emptydirectory

$ cd emptydirectory/
$ touch SConstruct
$ scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
