 Flatpak provides extensive tooling to give developers a working environment
 that is easy to setup and use: the framework provides the necessary tools and
 libraries for developers to create their application and is highly extensible.

 As the framework is composed of a set of different tools interacting with each
 other, it is also possible for the developer to use a classic developer workflow
 and use the command line to build and install an application. Guaranteeing the
