#
# Like Snap, Flatpak is another distribution independent package format aimed to simplify overall
# app distribution and usage in Linux systems. Previously known as xdg-app, the framework was based
# on the concept of running applications in a secure virtual sandbox without requiring root privileges
# or posing a security threat to the system.
# Flatpak was officially released in 2015 with a reliable backup from Red Hat, Endless Computers, and
# Collabora. It targeted primarily three Desktop Environments. That is FreeDesktop, KDE, and GNOME. The
# Linux distributions currently having this framework are arch Linux, Debian, Fedora, Mageia,
# Solus, and Ubuntu.The Flatpak framework itself is developed in C programming and released under the
# LGPL license. The lead developer is Alexander Larsson – a Red Hat employee. Like Snapcraft for Snap,
# Flatpak also has the Flathub app store where users can find and install all Flatpak packages.
# Initially, Flathub only allowed open-source publishing applications on the website but
# has recently approved the publishing of proprietary apps.
# Additionally, unlike Snap, where we have a single repository controlled by Canonical to install and update
# software packages, Flatpak supports the use of multiple repos. The one significant disadvantage with this
# package is the lack of support for Servers.
