This (POSIX) shell script takes a list of GitHub projects and tries finding, downloading and installing the correct deb/rpm/apk packages or compressed archives (currently only for `x86_64` Linux systems).
Unfortunately, I depend on that some pattern is used in the release's file names (like `xyz_linux_amd64.tar.gz`). So there is no guarantee that it works for every GitHub project. Just try it out and tell me when you find a project that you can't install with this script.
