+dnl There are several different values for --with-python:
+dnl
+dnl no - Don't include python support.
+dnl yes - Include python support, error if it's missing.
+dnl If we find python in $PATH, use it to fetch configure options,
+dnl otherwise assume the compiler can find it with no help from us.
+dnl Python 2.6, 2.5, and then 2.4 are tried in turn.
+dnl auto - Same as "yes", but if python is missing from the system,
+dnl fall back to "no".
+dnl /path/to/python/exec-prefix -
+dnl Use the python located in this directory.
+dnl If /path/to/python/exec-prefix/bin/python exists, use it to find
+dnl the compilation parameters. Otherwise use
+dnl -I/path/to/python/exec-prefix/include,
+dnl -L/path/to/python/exec-prefix/lib.
+dnl Python 2.6, 2.5, and then 2.4 are tried in turn.
+dnl NOTE: This case is historical. It is what was done for 7.0/7.1
+dnl but is deprecated.
+dnl /path/to/python/executable -
+dnl Run python-config.py with this version of python to fetch the
+dnl compilation parameters.
+dnl NOTE: This needn't be the real python executable.
+dnl In a cross-compilation scenario (build != host), this could be
+dnl a shell script that provides what python-config.py provides for
+dnl --ldflags, --includes, --exec-prefix.
+dnl python-executable -
+dnl Find python-executable in $PATH, and then handle the same as
+dnl /path/to/python/executable.
+dnl
+dnl If a python program is specified, it is used to run python-config.py and
+dnl is passed --ldflags, --includes, --exec-prefix.
