In far far too many code downloads is this nonsense:
You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
“Write to” – really? So you want to generate work for others?
Include the whole damn license – The file size overhead is not going to be an issue. – and/or link to the exceptionally well known websites that list the full GPL version you want to use.
Asking people to “write to” is lazy. Very lazy.
(FWIW I found this in a plugin downloaded from wordpress.org. Trust me, they can afford the space for the whole GPL txt file with every plugin.)
