[Marble] spelling junior job

[gkaukola at cs.ucr.edu]

Not exactly a spelling issue, but a lot of the license text I'm seeing at
the top of files is a bit strange.  Particularly this part:

    You should have received a copy of the GNU Library General Public License
    aint with this library see the file COPYING.LIB.  If not, write to
    the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor,
    Boston, MA 02110-1301, USA.

It seems like a sentence was left out perhaps?
