#  Runs the complete process of building a Linux AppImage.
#  The BUNDLED_CERTS option is very important as otherwise curl will not work on all
#  distributions as for example Debian-based systems place the TLS certificates in a
#  different location under /etc than Fedora and openSUSE.

#  This script has only been tested on Ubuntu 20.04 LTS. It's recommended to only build
#  AppImages on this operating system for maximum compatibility.
