It should be there
Important Note: Version 3 of CELstart is the first one that works for python scripts. However there is still a limitation. You have to manually set the PYTHONPATH environment variable to point to the zip file (i.e. not the extracted zip file, just the zip file itself) that you want to run. We will try to fix this limitation in the future.
The next release is coming soon though hopefully and this will be fixed.
