 =head1 DESCRIPTION
 
 Various places throughout the Bugzilla codebase need to report errors to the
 user. The C<Throw*Error> family of functions allow this to be done in a
 generic and localisable manner.
 
+These functions automatically unlock the database tables, if there were any
+locked. They will also roll back the transaction, if it is supported by
+the underlying DB.
