This script will install mma, the standard library and the
python modules.

YOU WILL NEED TO BE LOGGED IN AS ROOT TO CONTINUE!

We recommend that you install the package with this script
in the default locations. This script will create a
directory 'mma' in /usr/local/share. If this isn't
what you want, then stop this script and edit this
script's directory locations. But, please note that ONLY
/usr/local/share and /usr/share are supported as default
locations.

The main executable script will be installed in /usr/local/bin.

If you ever decide to get rid of MMA, just delete the executable
in /usr/local/mma and the directory tree in /usr/local/share/mma.
