the values of [parameters | bound parameters].
<li>Performance optimizations targetting a specific use case from
a single high-profile user of SQLite.  A 12% reduction in the number of

We believe that [http://www.ge.com/ | General Electric]
uses SQLite in some product or 
another because they twice wrote the to SQLite developers requesting 
the US Export Control Number for SQLite. So presumably GE is using
SQLite in something that they are exporting. But nobody
(outside of GE) seems to know what that might be.
