+# podman-try - try running a command via PODMAN1; use PODMAN2 as fallback
+#
+# Intended for use with a podmanv2 client. If a command isn't yet
+# implemented, fall back to regular podman:
+#
+# Set PODMAN_V2 to the path to a podman v2 client
+# Set PODMAN_FALLBACK to the path to regular podman
+#
+# THIS IS IMPERFECT. In particular, it will not work if stdin is redirected
+# (e.g. 'podman ... < file' or 'something | podman'); nor for anything
+# that generates continuous output ('podman logs -f'); and probably more
+# situations.
