-#
-# Purpose
-# -------
-# This runs ssl-opt.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-# WARNING: the Dockerfile used by this script is no longer maintained!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" 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.
-# - ssl-opt.sh for notes about invocation of that script.
