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 affidavi ts dedicating thei r contributions to the p ublic domain and origi nals of those signed
affidavits are sto red in a firesafe at the main offi ces of HYPERLINK “http ://www.hwaci.com”Hwa ci. Anyone is
free to copy, modify, publish, use , compile, sell, or dis tribute the orig inal SQLite code, ei ther in source code form
or as a compiled binary, for a ny purpose, commer cial or non-comme rcial, and by any means .
The previous parag raph applies to the delive rable code in SQLite - thos e parts of the SQLite lib rary 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 f all under other licenses. T he details here are uncl ear. 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 deliverabl e code in SQLite has been w ritten from scr atch. No code has been t aken from other proje cts
or from the open inter net. Every line of co de can be traced back to i ts original aut hor, and all of those author s have
public domain dedications on file. So the SQLite code base is clean and is uncontaminated with licensed code from
other projects.
