[docs] os.EX_NOTFOUND

[Omar Zabaneh]

Hi,

The exit code os.EX_NOTFOUND is not defined using Python 2.7.3 on
Linux (RedHat Enterprise).
I get the following error.
AttributeError: 'module' object has no attribute 'EX_NOTFOUND'

It seems like it is removed but that is not indicated in the documentation:
http://docs.python.org/2/library/os.html#os.EX_NOTFOUND

Thanks,
Omar
