# Teach pylint how api object works
#
# ipalib uses some tricks to create api.env members and api objects. pylint
# is not able to infer member names and types from code. The explict
# assignments inside the string builder templates are good enough to show
# pylint, how the api is created. Additional transformations are not
# required.
