# Script to be inlined into the main test scripts. Defines function 'setup()'
# which wraps around 'taler-unified-setup.sh' to launch GNU Taler services.
# Call setup() with the arguments to pass to 'taler-unified-setup'. setup()
# will then launch GNU Taler, wait for the process to be complete before
# returning. The script will also install an exit handler to ensure the GNU
# Taler processes are stopped when the shell exits.
