IFER: Install From External Repository

Introducing IFER, a new command line tool to speed up some common apt operations.
Are you tired of the boring process of installing packages from external repositories manually?
These are the commands you would normally need under a Debian environment to install lollitude-wtf from ppa:lollitudesoft:
sudo add-apt-repository ppa:lollitudesoft
sudo apt-get update
sudo apt-get install lollitude-wtf

Well, with IFER this is no more a problem! You would just have to run:
sudo ifer -i lollitude-wtf ppa:lollitudesoft

And that's it! No more problems!
Now imagine that you wanted to install the new ipear-music-player from ppa:ipear-os, the official system ipear-os repository, but installing that repository would require some "system updates" that change your already existing packages to the one from ipear-os. That would probably brake your installation! So you would have to remove the repository manually after the package installation.
With IFER this is just easier, all you have to do is running:
sudo ifer -iR ipear-music-player ppa:ipear-os

And here you are! The new music player is installed and your system is OK!

And how much would you pay for it?
200$?
50$?
A penny?

NO: IT'S FREE SOFTWARE!
