HI, I was just getting a feel for the codebase & noticed the cfa script has a specific user/path Python shebang at the very top, before the standard generic user one.

I suspect this is left in from a Python 3 porting development stage, as I can't see a purpose it would serve generally, & there is no equivalent Python 2 line in the earlier version of the same script up on Bitbucket.

I thought it would be easier to put in a PR to suggest to remove it than to write up an Issue. Thanks.
