conffile = 'env_check.conf'														# Set the variable conffile
conffilename=os.path.join(confdir, conffile)								# Set the variable conffilename by joining confdir and conffile together

for env_check in open(conffilename):										# Open the config file and read all the settings
  env_check = env_check.strip()												# Set the variable as itsself, but strip the extra text out
  print '[{}]'.format(env_check)													# Format the Output to be in Square Brackets
  newenv = os.getenv(env_check)											# Set the variable newenv to get the settings from the OS what is currently set for the settings out the configfile
  if newenv is None:																# If it doesn't exist
    print env_check, 'is not set'													# Print it is not set
  else:																					# Else if it does exist
    print 'Current Setting for {}={}\n'.format(env_check, newenv)	# Print out the details
