Description

Originally reported by: zahari_dim (Bitbucket: zahari_dim, GitHub: Unknown)


When a script is installed with setuptools, querying for the __spec__ of that mudule, yields an AttributeError.
This is mandatory in recent version of python, and gives errors with multiprocesing, like explained here:

http://stackoverflow.com/questions/24799146/use-multiprocessing-process-inside-a-script-installed-by-setuptools

Also, I would like a way for setuptools to just copy my scripts instead of messing with them as in this case.

Research direction

Start by reproducing the missing spec on a script installed with setuptools, using the multiprocessing failure described in the issue as the behavioral reference. Review the script-installation path and determine whether the fix should restore spec, provide a copy-without-modification option, or both; done means installed scripts support the reported query without causing the documented multiprocessing error.
