=head1 NAME
DBIx::Class::Schema::Loader::DBI::SQLite - DBIx::Class::Schema::Loader::DBI SQLite Implementation.
-=head1 SYNOPSIS
-
- package My::Schema;
- use base qw/DBIx::Class::Schema::Loader/;

- __PACKAGE__->loader_options( debug => 1 );

- 1;

=head1 DESCRIPTION
-See L<DBIx::Class::Schema::Loader::Base>.
+See L<DBIx::Class::Schema::Loader> and L<DBIx::Class::Schema::Loader::Base>.
=head1 METHODS
=head2 rescan
-SQLite will fail all further commands on a connection if the
-underlying schema has been modified. Therefore, any runtime
-changes requiring C<rescan> also require us to re-connect
-to the database. The C<rescan> method here handles that
-reconnection for you, but beware that this must occur for
-any other open sqlite connections as well.
