Private pythonpath in a ._pth file

Hi,
Would it be possible to ship the builds including a private pythonpath defined in a file?
The common portable windows python from python.org contains a ._pth file where the pythonpath is defined. So you can install your software with the included python without distracting any other python installation using the system pythonpath.
It would be cool to have this option on linux too. If one would like to use the system pythonpath, the ._pth file can easily be deleted.
