+Functional tests for the System Admin Toolkit (SAT).
+
+This script is a thin wrapper around the unittest module. This script is used
+instead of directly using `python -m unittest` because the build scripts in this
+repository install this script in the Python virtual environment in which the
+csm_testing module is installed and then create a symlink to the script. This
+script will thus be able to automatically find the unittest test cases defined
+in the directories within this directory.
+
+This script also prepends the arguments it's given with the parent package name
+in order to shorten the calls made in the Goss test files.
+
+For example:
+
+  `python -m unittest csm_testing.tests.sat_functional.version.TestVersion.test_version`
+
+becomes:
+
+  `sat_functional version.TestVersion.test_version`
