SQLite Copyright

All of the deliverable code in SQLite has been dedicated to the public domain by the authors. 
All code authors, and representatives of the companies they work for, have signed affidavits 
dedicating their contributions to the public domain and originals of those signed affidavits 
are stored in a firesafe at the main offices of Hwaci. Anyone is free to copy, modify, publish, 
use, compile, sell, or distribute the original SQLite code, either in source code form or as a 
compiled binary, for any purpose, commercial or non-commercial, and by any means.

The previous paragraph applies to the deliverable code in SQLite - those parts of the SQLite 
library that you actually bundle and ship with a larger application. Portions of the documentation
and some code used as part of the build process might fall under other licenses. The details 
here are unclear. We do not worry about the licensing of the documentation and build code so 
much because none of these things are part of the core deliverable SQLite library.

All of the deliverable code in SQLite has been written from scratch. No code has been taken 
from other projects or from the open internet. Every line of code can be traced back to its 
original author, and all of those authors have public domain dedications on file. So the SQLite 
code base is clean and is uncontaminated with licensed code from other projects.
