+** This file contains code for the "fts3tokenize" virtual table module.
+** An fts3tokenize virtual table is created as follows:
+**
+** CREATE VIRTUAL TABLE <tbl> USING fts3tokenize(
+** <tokenizer-name>, <arg-1>, ...
+** );
+**
+** The table created has the following schema:
+**
+** CREATE TABLE <tbl>(input, token, start, end, position)
+**
+** When queried, the query must include a WHERE clause of type:
+**
+** input = <string>
+**
+** The virtual table module tokenizes this <string>, using the FTS3
+** tokenizer specified by the arguments to the CREATE VIRTUAL TABLE
+** statement and returns one row for each token in the result. With
+** fields set as follows:
+**
+** input: Always set to a copy of <string>
+** token: A token from the input.
+** start: Byte offset of the token within the input <string>.
+** end: Byte offset of the byte immediately following the end of the
+** token within the input string.
+** pos: Token offset of token within input.
