Dell 926 All In One Inkjet Printer - Příručka (Stránka 112)

If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend
making it free software that everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License).
To apply these terms, attach the following notices to the library. It is safest to attach them to the start of
each source file to most effectively convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
