 1. I've used *reasonable* arguments for `wget` in the script. There currently is no need to use different arguments nor is there a way to supply your own arguments to the `wget` instance in this script. Feel free to modify them in the script itself or add a way for you to pass them into the script via a parameter(s). In that case I would welcome a pull request! :) I however do not currently need this functionality.
