This is from the top of sqlite3.h, the header file for the SQLite3 library – most source file would have a copyright notice here referring people to read their license, but since SQLite is public domain, the author decided to put this instead:
** The author disclaims copyright to this source code. In place of
** a legal notice, here is a blessing:
** May you do good and not evil.
** May you find forgiveness for yourself and forgive others.
** May you share freely, never taking more than you give.
I have to admit I find this inspiring. For me, it is a strong reminder that dealing with legal limitations (on software and any other form of “intellectual property”) is at best no more than a necessary evil. That goes for free software licensing as well.
