17. SQLite
All of the deliverable code in SQLite has been dedicated to the HYPERLINK "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.
