Difference between entry_points/console_scripts and scripts in setup.py?

The docs for the (awesome) Click package suggest a few reasons to use entry points instead of scripts, including

1. cross-platform compatibility and
2. avoiding having the interpreter assign __name__ to __main__, which could cause code to be imported twice (if another module imports your script)

Click is a nice way to implement functions for use as entry_points, btw.

One key difference between these two ways of creating command line executables is that with the setuptools approach (your first example), you have to call a function inside of the script -- in your case this is the func inside of your module. However, in the distutils approach (your second example) you call the script directly (which allows being listed with or without an extension).

The setup tools entry point approach (#1) also has the benefit that on windows an .exe will be created that can be double clicked and invoked like a regular windows program. This is in addition to having a script placed in the bin path on posix-like systems.

One more difference is that when using console_scripts, my module's __init__ file was run. When just using scripts, the module __init__ was not run, only the script was run.
