-** Code for testing the virtual table interfaces.  This code
-** is not included in the SQLite library.  It is used for automated
-** testing of the SQLite library.
-**
-** The FS virtual table is created as follows:
-**
-**   CREATE VIRTUAL TABLE tbl USING fs(idx);
-**
-** where idx is the name of a table in the db with 2 columns.  The virtual
-** table also has two columns - file path and file contents.
-**
-** The first column of table idx must be an IPK, and the second contains file
-** paths. For example:
-**
-**   CREATE TABLE idx(id INTEGER PRIMARY KEY, path TEXT);
-**   INSERT INTO idx VALUES(4, '/etc/passwd');
-**
-** Adding the row to the idx table automatically creates a row in the 
-** virtual table with rowid=4, path=/etc/passwd and a text field that 
-** contains data read from file /etc/passwd on disk.
