copyleft
     
         /kop'ee-left/ a play on "copyright" the copyright
        notice and general public license applying to the works of
        the free software foundation, granting reuse and
        reproduction rights to everyone.
     
        typically copyrights take away freedoms; copyleft preserves
        them.  it is a legal instrument that requires those who pass
        on a program to include the rights to use, modify, and
        redistribute the code; the code and the freedoms become
        legally inseparable.
     
        the copyleft used by the gnu project combines a regular
        copyright notice and the "gnu general public license" gpl.
        the gpl is a copying license which basically says that you
        have the aforementioned freedoms.  the license is included in
        each gnu source code distribution and manual.
     
        see also general public virus.
