# Ubuntu installer script
#
# This script either installs FinalCif vom the source repository or simply runs FinalCif.
# Prior to installation, a recent Python version is needed.
# Everything (except Python3) is installed below the ./FinalCif directory and nowhere else.
# This script might work in other Linux distributions, except for the -pyinst option.
#
# Commandline Options:
#
# ./finalcif-start.sh [-option]
#
# -pyinst : Adds a Python repository (deadsnakes) and installs Python3.9
# -install : Install FinalCif from GitHub. The installer asks about the version number to install.
# Use 'trunk' as version to get the most recent unstable source code.
#
# without any option: Run FinalCif
