Is there a way to install a package via a simple URL without having to add a PPA beforehand? Something like apt-get https://url.to.package.deb? Or perhaps some command line options that would add the PPA, update, and install the package all at once? Seems like I've seen other package managers that do this. I just find it a hassle to type the commands to add a whole repository just so I can install only one of its packages.
