# This container builds Plom's AppImage, a portable single-file for GNU/Linux

# I first tried `FROM appimage-builder` but failed with fontconfig errors.

# Instead of running this file you can execute the commands interactively,
# e.g., inside `podman run -it --rm -v ./:/media:z ubuntu:20.04`.
#
# Do we want to keep Ubuntu back on 20.04 to have earliest supported OS?
#
# TODO: what bits of our source code to put in src?
