   <p>
    AX_PYTHON_CONFIG_VAR:
   </p>
   <p>
    Using the Python module distutils.sysconfig[1], return a Python
    configuration variable. PYTHON_VARIABLE is the name of the variable to
    request from Python, and SHELL_VARIABLE is the name of the shell variable
    into which the results should be deposited. If SHELL_VARIABLE is not
    specified, the macro wil prefix PY_ to the PYTHON_VARIABLE, e.g., LIBS
    -&gt; PY_LIBS.
   </p>
   <p>
    SHELL_VARIABLE is AC_SUBST'd. No action is taken if an error occurs. Note
    if $PYTHON is not set, AC_CHECK_PROG(PYTHON, python, python) will be run.
   </p>
   <p>
    Example:
   </p>
   <pre>
  AX_PYTHON_CONFIG_VAR(LINKFORSHARED, PY_LFS)
</pre>
   <p>
    AX_PYTHON_CONFIG_H:
   </p>
   <p>
    Using the Python module distutils.sysconfig[1], put the full pathname of
    the config.h file used to compile Python into the shell variable
    PY_CONFIG_H. PY_CONFIG_H is AC_SUBST'd. Note if $PYTHON is not set,
    AC_CHECK_PROG(PYTHON, python, python) will be run.
   </p>
   <p>
    AX_PYTHON_MAKEFILE:
   </p>
   <p>
    Using the Python module distutils.sysconfig[1], put the full pathname of
    the Makefile file used to compile Python into the shell variable
    PY_MAKEFILE. PY_MAKEFILE is AC_SUBST'd. Note if $PYTHON is not set,
    AC_CHECK_PROG(PYTHON, python, python) will be run.
