# Builds the Python Spread wrapper module.
# Puts:
#     spread.pyd into build/lib/python/
#     testspread.py into build/lib/python/SpreadTest/
#     various text files (Windowsized and renamed) into build/doc

# Download the wrapper module tarball, from
# http://www.python.org/other/spread/.
# Store it in tmp/.  NOTE:  May need to rename it to .tgz (depends on how
# it's downloaded).  The name is of the form SpreadModule-n.n.tgz

# XXX There's no natural way to clean up SPREADWRAPPER_TMPDIR here.
