<p>
All of the code and documentation in SQLite has been dedicated to the
[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

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.

<h2>Obtaining An License To Use SQLite</h2>

<p>
Even though SQLite is in the public domain and does not require
a license, some users want to obtain a license anyway.  Some reasons
for obtaining a license include:
</p>

<ul>
<li> Your company desires warranty of title and/or
     indemnity against claims of copyright infringement.
<li> You are using SQLite in a jurisdiction that does not recognize
     the public domain.  </li>
<li> You are using SQLite in a jurisdiction that does not recognize
     the right of an author to dedicate their work to the public
     domain. </li>
<li> You want to hold a tangible legal document
     as evidence that you have the legal right to use and distribute
     SQLite. </li>
<li> Your legal department tells you that you have to purchase a license.
     </li>
</ul>

<p>
If you feel like you really need to purchase a license for SQLite,
<a href="http://www.hwaci.com/">Hwaci</a>, the company that employs 
all the developers of SQLite, will 
<a href="http://www.hwaci.com/cgi-bin/license-step1">sell you
one</a>.
All proceeds from the sale of SQLite licenses are used to fund
continuing improvement and support of SQLite.
</p>

<h2>Contributed Code</h2>

<p>
In order to keep SQLite completely free and unencumbered by copyright,
all new contributors to the SQLite code base are asked to dedicate

<h2>Most Widely Deployed and Used Database Engine</h2>

<p>SQLite is likely used more than all other database engines
combined.  Billions and billions of copies
of SQLite exist in the wild.  SQLite is found in:

<tcl>hd_keywords {serverless} {embedded}</tcl>

<h2>SQLite Is Serverless</h2>

<p>
Most SQL database engines are implemented as a separate server process.
Programs that want to access the database communicate with the server
using some kind of interprocess communication (typically TCP/IP) to send

<h2>SQLite Is A Zero-Configuration Database</h2>

<p>
SQLite does not need to be "installed" before it is used. 
There is no "setup" procedure.  There is no
server process that needs to be started, stopped, or configured.
