-
-  Use :module:`FindPython3`, :module:`FindPython2` or :module:`FindPython` instead.
-
-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).
-
-If calling both ``find_package(PythonInterp)`` and
-``find_package(PythonLibs)``, call ``find_package(PythonInterp)`` first to
-get the currently active Python version by default with a consistent version
-of PYTHON_LIBRARIES.
-
-.. note::
-
-  A call to ``find_package(PythonInterp ${V})`` for python version ``V``
-  may find a ``python`` executable with no version suffix.  In this case
-  no attempt is made to avoid python executables from other versions.
-  Use :module:`FindPython3`, :module:`FindPython2` or :module:`FindPython`
-  instead.

-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(PythonLibs).
-
-If you'd like to specify the installation of Python to use, you should
-modify the following cache variables:
-
-::
-
-  PYTHON_LIBRARY             - path to the python library
-  PYTHON_INCLUDE_DIR         - path to where Python.h is found
-
-If calling both ``find_package(PythonInterp)`` and
-``find_package(PythonLibs)``, call ``find_package(PythonInterp)`` first to
-get the currently active Python version by default with a consistent version
-of PYTHON_LIBRARIES.
