+<p>A <a href="vtab.html">virtual table</a> is an object that presents an SQL table
+interface but which is not stored in the database file, at least
+not directly.  The virtual table mechanism is a feature
+of SQLite that allows SQLite to access and manipulate resources
+other than bits in the database file using the powerful SQL
+query language.
+
+</p><p>
+The table below lists a few of the virtual tables implementations
+available for SQLite.  Developers can deploy these virtual tables
+in their own applications, or use the implementations shown below
+as templates for writing their own virtual tables.
+
+</p><p>
+The list below is not exhaustive.
+Other virtual table implementation exist in the SQLite source tree
+and elsewhere.
+The list below tries to capture the more interesting virtual table
+implementations.
