Have multiple environments and need to pass in a config file based on the environment?

Use this, so you don't pass the wrong config.

Use:

#!/usr/bin/python
import enviro_check
class Main:
    def __init__(self, configFile):
        pass
 
    def process(self):
        print "ok"
 
if __name__ == "__main__":
    m = Main(entryscript.CONFIGFILE)
    m.process()
