Correct, python-software-properties adds the:
apt-add-repository/add-apt-repository command
It's a one time thing of course, if you've ever used it to add other
ppas from Launcpad. Basically it knows how to find the correct launchpad
url and key.
The alternative is to add the repos yourself to sources.list or
sources.list.d, then to download and apt-add the key those repos are
signed with. The above tool does all of that for you.
Enjoy,
Alex
