# Possible arguments:
#  - the version of the xfce-build container (if you want to build with a special version)
#  - 'pull' to simply update the container and exit
#  - 'version' as second positional argument after an actual version (e.g. xfce-build latest version)
#     to print all git versions built in the container by build_libs.sh
