# - Find python libraries
# This module finds if Python is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#
#  PYTHON_LIBRARIES     = path to the python library
#  PYTHON_INCLUDE_PATH  = path to where Python.h is found
#  PYTHON_DEBUG_LIBRARIES = path to the debug library
#
