define Package/python3/Default/description
 Python is a dynamic object-oriented programming language that can be used
 for many kinds of software development. It offers strong support for
 integration with other languages and tools, comes with extensive standard
 libraries, and can be learned in a few days. Many Python programmers
 report substantial productivity gains and feel the language encourages
 the development of higher quality, more maintainable code.

#=======================================================================
# Notes: adding these so that I don't forget, and can track why stuff
#        was did as was did
# - Arguments below were moved to ./files/config.site file, and disabled
#          ac_cv_have_chflags=no \
#          ac_cv_have_lchflags=no \
#          ac_cv_py_format_size_t=no \
#          ac_cv_have_long_long_format=yes \
#          ac_cv_buggy_getaddrinfo=no \
# - --without-ensurepip added, because the build wants to ensure that
#   it works; that's a good idea, but for now, it requires special 
#   setup, and we can do that later
# - --without-pymalloc added, becase in Python 3, modules are suffixed
#   with m; e.g. so some paths are python3.4m instead of python3.4 
#   all this is detailed here:
#     http://legacy.python.org/dev/peps/pep-3149/
