# Maze of Python-related tests is complicated.
#
# - If we don't have Python at all, we can't run any of the Python
# tools and probably should not even attempt to configure them.
#
# - If the system Python executable was linked against OpenSSL -and-
# we had to build our own copy of OpenSSL (because the system copy
# wasn't good enough), we need to build pywrap and configure scripts
# to use it.
#
# - Otherwise (we have python and it's not linked against the wrong
# version of OpenSSL), we can use the system Python executable and
# don't need pywrap.
#
# - Unless we're punting on Python entirely, we need to build POW,
# either against the system OpenSSL or against our own copy.
#
# - If we're building either POW or pywrap, we need Python.h.
#
# If any of this fails, we need to tell the user and give useful hint
# on what to do next (doc reference, whatever).
#
# Oh, and the user has to be able to override all of our guessing,
# with --enable/--disable or whatever autoconf hack we're using this
# week.
# This isn't the complete list of Makefiles (let alone setup.py, etc
# files) in this tree, just the ones we're customizing today. At some
# point I should do a pass through the rest of the tree, making clever
# use of abs_top_builddir, etc.
