Directly install applications from their GitHub repository with out-of-the-box support for updates using GPM, the package manager with the superpowers of a cross-platform build tool. GPM brings the following:

Any open source repository on GitHub is available to install as a package. As soon as you publish your repository on GitHub, it's available for installing with gpm-cli. You can roll back the installed updates on any package. You can even install a specific tag/version of any repository. You can control which apps should receive updates. You can update any package individually or update all of them at once. You can even build a repository from source.
