# install_flash_player_11_linux.i386.tar.gz file is at
# on Ubuntu 10.04 to install the new flash player in such
# a way that you can go back to the old one.  You may need
# to copy all of the image and other files manually but I
# have found you only need to do it once for each major
# version of Flash - so far.  But you do have a way of
# backing up to the previous version of flash if you have
# problems.  No warranty is made that it will work,
# especially for other versions of Ubuntu, much less some
# other distro.
