"http://en.wikipedia.org/wiki/Public_Domain"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 HYPERLINK "http://www.hwaci.
com"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.
