# This script fulfills all requirements in an Ubuntu 22.04 environment to build the AppImage for sast-scan
# It might work in other debian based environments but it has not been tested.
# Furthermore, the AppImage Process does add ubuntu repositories for 22.04 so it is not guaranteed to work outside
# of that environment (or derivatives).
# AppImage generation is rather slow by nature and this script installs a set of packages, we recommend running it
# within the confines of an LXC container or similar.

# Install all dependencies that come from the distro package manager.
