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

748 dnl NOTE: This case is historical. It is what was done for 7.0/7.1
749 dnl but is deprecated.
750 dnl /path/to/python/executable -
751 dnl Run python-config.py with this version of python to fetch the
752 dnl compilation parameters.
753 dnl NOTE: This needn't be the real python executable.
754 dnl In a cross-compilation scenario (build != host), this could be
755 dnl a shell script that provides what python-config.py provides for
756 dnl --ldflags, --includes, --exec-prefix.
757 dnl python-executable -
758 dnl Find python-executable in $PATH, and then handle the same as
759 dnl /path/to/python/executable.
761 dnl If a python program is specified, it is used to run python-config.py and
762 dnl is passed --ldflags, --includes, --exec-prefix.
