I've spent some time trying to nicely format an GPL excerpt in LaTeX. The problem is that the all-caps text of the "no warrantly" section doesn't fit to the TeX rules well. Finally, I gave up and decided to find out how this problem is handled by other people. I found the GNU General Public License (GPL) in LaTeX format on the official site gnu.org. Surprise! They don't have a solution, they have a workaround. The all-caps text is converted to normal text. I like it. The workaround is adopted.
