+# Environment to execute the WALinuxAgent unit tests for some versions of Python that have reached EOL and are no longer available
+# in the official repositories.
+#
+# To build the image, set the PYTHON_VERSION argument to 2.6 or 3.4:
+#
+#    * docker build -t python2.6 --build-arg PYTHON_VERSION=2.6 .
+#    * docker build -t python3.4 --build-arg PYTHON_VERSION=3.4 .
+#
+# Sample commands (note that the convenience functions defined in the profile assume the root of the source code has been mounted at /home/waagent/WALinuxAgent):
+#
+#    * Start an interactive session: docker run --rm -it -v WALinuxAgent:/home/waagent/WALinuxAgent bash --login
+#    * Run unit tests:               docker run --rm -v WALinuxAgent:/home/waagent/WALinuxAgent python2.6 bash --login -c run-tests
+#    * Run tests that require root:  docker run --user root --rm -v WALinuxAgent:/home/waagent/WALinuxAgent python2.6 bash --login -c run-sudo-tests
