    1.31 +# of the virtual table is a prefix of the name of the underlying
    1.32 +# real table (for example if the v-table is "tbl" and the real table
    1.33 +# is "tbl_base"), then the name of the real table is modified
    1.34 +# when an "ALTER TABLE ... RENAME TO" is executed on the v-table.
    1.35 +# For example:
    1.36 +#
    1.37 +#   sqlite> CREATE TABLE t1_base(a, b, c); 
    1.38 +#   sqlite> CREATE VIRTUAL TABLE t1 USING(t1_base);
