pyconf will automatically generate a setup.py.in file,
to be configured by the configure script to produce the Python
setup.py script. If the --prefer-make option was
specified, this file will merely contain Python code which calls Make
on the generated Makefile, and needs not to be
modified. Otherwise, the file will contain basic Python code to use
distutils for package installation. The reader is referred to
the Python documentation for more information on how to customize this
file.
