+# compat-in-docker.sh
+#
+# Purpose
+# -------
+# This runs compat.sh in a Docker container.
+#
+# WARNING: the Dockerfile used by this script is no longer maintained! See
+# https://github.com/Mbed-TLS/mbedtls-test/blob/master/README.md#quick-start
+# for the set of Docker images we use on the CI.
+#
+# Notes for users
+# ---------------
+# If OPENSSL, GNUTLS_CLI, or GNUTLS_SERV are specified the path must
+# correspond to an executable inside the Docker container. The special
+# values "next" (OpenSSL only) and "legacy" are also allowed as shorthand
+# for the installations inside the container.
+#
+# See also:
+# - scripts/docker_env.sh for general Docker prerequisites and other information.
+# - compat.sh for notes about invocation of that script.
