732 dnl There are several different values for --with-python:
734 dnl no - Don't include python support.
735 dnl yes - Include python support, error if it's missing.
736 dnl If we find python in $PATH, use it to fetch configure options,
737 dnl otherwise assume the compiler can find it with no help from us.
738 dnl Python 2.7, 2.6, 2.5, and then 2.4 are tried in turn.
739 dnl auto - Same as "yes", but if python is missing from the system,
740 dnl fall back to "no".
741 dnl /path/to/python/exec-prefix -
742 dnl Use the python located in this directory.
743 dnl If /path/to/python/exec-prefix/bin/python exists, use it to find
744 dnl the compilation parameters. Otherwise use
