// SQLite Is Public Domain
// 
// All of the code and documentation 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 and documentation in
// SQLite - those parts of the SQLite library that you actually bundle and ship
// with a larger application. Some scripts used as part of the build process
// (for example the "configure" scripts generated by autoconf) might fall under
// other open-source licenses. Nothing from these build scripts ever reaches
// the final deliverable SQLite library, however, and so the licenses
// associated with those scripts should not be a factor in assessing your
// rights to copy and use the 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.
