=head1 DEPRECATED

I begrudgingly made this module (and other related modules) to keep porting
from L<DBIx::Class::Schema::Versioned> relatively simple.  I will make changes
to ensure that it works with output from L<DBIx::Class::Schema::Versioned> etc,
but I will not add any new features to it.

Once I hit major version 1 usage of this module will emit a warning.
On version 2 it will be removed entirely.

=head1 THIS SUCKS

Here's how to convert from that crufty old Deprecated VersionStorage to a shiny
new Standard VersionStorage:

 my $s  = My::Schema->connect(...);
 my $dh = DeploymentHandler({
   schema => $s,
 });

 $dh->prepare_version_storage_install;
 $dh->install_version_storage;

 my @versions = $s->{vschema}->resultset('Table')->search(undef, {
   order_by => 'installed',
 })->get_column('version')->all;

 $dh->version_storage->add_database_vesion({ version => $_ })
   for @versions;

=head1 SEE ALSO

This class is an implementation of
L<DBIx::Class::DeploymentHandler::HandlesVersionStorage>.  Pretty much all the
documentation is there.
