 # Test Organisation:
 # ------------------
 #
 # alter4-1.*: Test that ALTER TABLE correctly modifies the CREATE TABLE sql.
 # alter4-2.*: Test error messages.
 # alter4-3.*: Test adding columns with default value NULL.
 # alter4-4.*: Test adding columns with default values other than NULL.
 # alter4-5.*: Test adding columns to tables in ATTACHed databases.
 # alter4-6.*: Test that temp triggers are not accidentally dropped.
 # alter4-7.*: Test that VACUUM resets the file-format.
 #
 
-# This procedure returns the value of the file-format in file 'test.db'.
