+# - 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_VERSION_STRING      - Python version found e.g. 2.5.2
+#  PYTHON_VERSION_MAJOR       - Python major version found e.g. 2
+#  PYTHON_VERSION_MINOR       - Python minor version found e.g. 5
+#  PYTHON_VERSION_PATCH       - Python patch version found e.g. 2
+#
+# The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of
+# version numbers that should be taken into account when searching for Python.
+# You need to set this variable before calling find_package(PythonInterp).
+#
+# You can point to a preferred python install to use by setting the following
+# to the point at the root directory of the python install:
+#
+#  PYTHON_ROOT_DIR            - The root directory of the python install
