# Upstream lives in the Sun Download Center, which normally requires a login
# and limits the number of times you can download the package, /however/, the
# download link from the project page at http://research.sun.com/brazil/ goes
# to a page that performs some magic that apparently obviates all of these
# restrictions entirely. Considering that this magic is performed by one of
# upstream's own pages, I think it's fair to use that mechanism to download it,
# which is the reason for the following bit of fruity script:
