    Porter's handbook: GPL licenses installation
    
    As 13.20 kindly asks to avoid installing more GNU General Public License
    files into our system,
    
    - Repeat this recommendation in 5.7.
    - Modify an example in 5.7 going against that recommendation by
      replacing GPLv3+ with BSD2CLAUSE.
