=head1 NAME
DBIx::Connector::Driver::SQLite - SQLite-specific connection interface
=head1 DESCRIPTION
This subclass of L<DBIx::Connector::Driver|DBIx::Connector::Driver> provides
SQLite-specific implementations of the following methods:
=over
=item C<savepoint>
=item C<release>
=item C<rollback_to>
=back
Note that they only work with SQLite 3.6.8 or higher; older versions of SQLite
will fallback on the exception-throwing implementation of these methods in
L<DBIx::Connector::Driver|DBIx::Connector::Driver>.
