setup.py weird format, slower

[HDembinski]

setup.py has a weird format, that is highly non-standard for a setup.py.

1. One does not use if __name__ == "__main__" in setup.py, because it is never imported as a module. It is always executed as a script.

2. Constructing the arguments to setup(...) separately in a dict is slower than just passing the arguments directly to setup(...). There is no advantage in doing it the way you do.

Hi Hans,

sorry, I've noticed this now :)

I'm doing this for the version argument to be importable in docs/conf.py, without importing anything else that requires the execution of setup.py. The intention is to keep the version number in setup.py and docs synchronized. I'm happy to change this to anything else.
