740 dnl There are several different values for --with-python:

743 dnl yes - Include python support, error if it's missing.
744 dnl If we find python in $PATH, use it to fetch configure options,
745 dnl otherwise assume the compiler can find it with no help from us.
746 dnl Python 2.7, 2.6, 2.5, and then 2.4 are tried in turn.
747 dnl auto - Same as "yes", but if python is missing from the system,
748 dnl fall back to "no".
749 dnl /path/to/python/exec-prefix -
750 dnl Use the python located in this directory.
751 dnl If /path/to/python/exec-prefix/bin/python exists, use it to find
752 dnl the compilation parameters. Otherwise use

755 dnl Python 2.7, 2.6, 2.5, and then 2.4 are tried in turn.
756 dnl NOTE: This case is historical. It is what was done for 7.0/7.1
757 dnl but is deprecated.
758 dnl /path/to/python/executable -
759 dnl Run python-config.py with this version of python to fetch the
760 dnl compilation parameters.
761 dnl NOTE: This needn't be the real python executable.
762 dnl In a cross-compilation scenario (build != host), this could be
763 dnl a shell script that provides what python-config.py provides for
764 dnl --ldflags, --includes, --exec-prefix.
765 dnl python-executable -
766 dnl Find python-executable in $PATH, and then handle the same as
767 dnl /path/to/python/executable.
769 dnl If a python program is specified, it is used to run python-config.py and
770 dnl is passed --ldflags, --includes, --exec-prefix.
