+# - Find python interpreter
+# This module finds if Python interpreter is installed and determines where the
+# executables are. This code sets the following variables:
+#
+#  PYTHONINTERP_FOUND         - Was the Python executable found
+#  PYTHON_EXECUTABLE          - path to the Python interpreter
+#  Python_ADDITIONAL_VERSIONS - list of additional Python versions to search for
