# - 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_DOC  - path to the Python documentation generator
#  PYTHON_COMPILE  - path to the Python compilerr
