+# The following checks for the right (i.e. most recent) Python binary available
+# and re-starts the script using that binary (like a shell wrapper).
+#
+# Using a shebang like "#!/bin/env python" on newer Fedora/Debian distros is banned [1]
+# and also won't work on other newer distros (Ubuntu >= 23.10), as those only ship
+# python3 without a python->python3 symlink anymore.
+#
+# Note: As Python 2 is EOL, we consider this last (and hope for the best).
