Now it looks like you're deleting this line.

I did delete it since this was merged in after my last submit. The change came
from someone else. I will add this back.

The only changes in this file should be these two lines. Nothing else

[dyu1, 2011/11/18 23:16:30]

It was difficult to make the adjustments since I have another CL with
PYAUTO_TEST pending approval. I'm using SVN and it doesn't handle multiple
changes to the same file across pending CLs very well.
