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

753 dnl NOTE: This case is historical. It is what was done for 7.0/7.1
754 dnl but is deprecated.
755 dnl /path/to/python/executable -
756 dnl Run python-config.py with this version of python to fetch the
757 dnl compilation parameters.
758 dnl NOTE: This needn't be the real python executable.
759 dnl In a cross-compilation scenario (build != host), this could be
760 dnl a shell script that provides what python-config.py provides for
761 dnl --ldflags, --includes, --exec-prefix.

763 dnl Find python-executable in $PATH, and then handle the same as
764 dnl /path/to/python/executable.
766 dnl If a python program is specified, it is used to run python-config.py and
