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

751 dnl If we find python in $PATH, use it to fetch configure options,
752 dnl otherwise assume the compiler can find it with no help from us.
753 dnl Python 2.7, 2.6, 2.5, and then 2.4 are tried in turn.
754 dnl auto - Same as "yes", but if python is missing from the system,
755 dnl fall back to "no".
756 dnl /path/to/python/exec-prefix -
757 dnl Use the python located in this directory.
758 dnl If /path/to/python/exec-prefix/bin/python exists, use it to find
759 dnl the compilation parameters. Otherwise use

763 dnl NOTE: This case is historical. It is what was done for 7.0/7.1
764 dnl but is deprecated.
765 dnl /path/to/python/executable -
766 dnl Run python-config.py with this version of python to fetch the
767 dnl compilation parameters.
768 dnl NOTE: This needn't be the real python executable.
769 dnl In a cross-compilation scenario (build != host), this could be
770 dnl a shell script that provides what python-config.py provides for

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