-Running `installJRMC` without any options will install the latest version of JRiver Media Center from the official JRiver repository (Ubuntu/Debian) or my [unofficial repository](https://repos.bryanroessler.com/jriver/) (Fedora/CentOS) using the system package manager. If any other option is specified then the default install method will need to be specified using `--install-repo` (or `--install-rpm`). This makes it possible to install services, containers, repos, etc. independent from Media Center.
