Support for Python 3.0, drop support for pre-2.0. * lib/py-compile: Do not import string; use sys.stdout.write instead of print, files.split instead of string.split. * m4/python.m4 (AM_PATH_PYTHON): Also look for python3 and phython3.0; do not look for python1.5. Use sys.stdout.write. (AM_PYTHON_CHECK_VERSION): Do not use string; adjust to xrange removal in Python 3.0, and changed semantics of map. * doc/automake.texi (Python, Hard-Coded Install Paths): Update Python versions mentioned in the manual, using 2.5 everywhere. * NEWS, THANKS: Update.
