You'll need to run this from a Linux system (it *might* be possible using perl on windows, but I haven't tried it at all, and suspect some of the modules may be non-trivial to get working).
First, create a CSV file containing your MAC addresses, AP names, and profiles to assign. Take a look at the sample waps.csv from the git repo. I highly reccomend you only start off with one or two to make sure it works for your setup first.
Now you can just run the script, passing it at least your controller name. You can override the defaults for the CSV name and username, and you will be prompted for passwords if you don't provide one. Just run the script with --help to see all of the available options.
