dnl Checks for Python and tries to get the include path to 'Python.h'.

dnl It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) output

|
dnl variables.
|
|
dnl Also exports $(PYTHON_EXTRA_LIBS) and $(PYTHON_EXTRA_LDFLAGS)
|

dnl for embedding Python in your code.

dnl If the user wants to employ a particular version of Python, she can
|
|
dnl now pass to configure the PYTHON_VERSION environment variable.
