(optional) I recommend adding a comment here that this environment variable is
assumed to have value "True" or "False" (until I realized that, I wasn't sure
why you were calling eval() on it).

[Nirnimesh, 2011/05/19 06:40:20]

Why do you need to eval it anyway?
Why not assume False if the env is missing, and True otherwise.

[imasaki1, 2011/05/20 05:12:01]

Changed based on Nirnimesh comments.

[imasaki1, 2011/05/20 05:12:01]

Done.

Also change other boolean environment valuables as well.
