+# Register the echo module.
+#
+# This test uses a special feature of the echo module. If the name
+# of the virtual table is a prefix of the name of the underlying
+# real table (for example if the v-table is "tbl" and the real table
+# is "tbl_base"), then the name of the real table is modified
+# when an "ALTER TABLE ... RENAME TO" is executed on the v-table.
+# For example:
+#
+#   sqlite> CREATE TABLE t1_base(a, b, c); 
+#   sqlite> CREATE VIRTUAL TABLE t1 USING(t1_base);
+#   sqlite> ALTER TABLE t1 RENAME TO t2;
+#   sqlite> SELECT tbl_name FROM sqlite_master;
+#   t2_base
+#   t2
