This simply puts your program's name into the copying permission statement for the GPL.
I know it's trivial but I got tired of doing it manually.
Put the generated code at the top of each file in your program.
You should also include a copy of the license itself somewhere in the distribution of your program. All programs, whether they are released under the GPL or LGPL, should include the text version of the GPL. In GNU programs the license is usually in a file called COPYING.
If you are releasing your program under the LGPL, you should also include the text version of the LGPL, usually in a file called COPYING.LESSER. Please note that, since the LGPL is a set of additional permissions on top of the GPL, it's important to include both licenses so users have all the materials they need to understand their rights.
