SOLVER=LTS and VERSION=22# will cause update-stackage.sh to fetch the latest LTS-22.XX version.# If empty, the latest version of the solver is used.## If the configuration file has been updated, update-stackage.sh prints a# version difference to stdout, e.g. 23.11 -> 23.13. Otherwise, stdout remains# empty.## EXIT STATUS## Always exit with zero (even if nothing changed) unless there was an error.
