Yes, in this constellation it is redundant. I never worked with Travis before and did not know that this can break the build. My initial idea was to leave it up to the user (that is why it is explained here in readme) whether to install `python-gflags` or not. I thought that the main purpose of Pylama is to check quality aspects of Python code, so not all users will use this to check JavaScript code. I want wanted to leave the choice to the user, so they do not have to install sth. they are not using. Do you know if there is any other way to leave is up to the user and make Travis build pass? Or would this be a wrong way in general ?
