=head1 SYNOPSIS

    package My::SQL::Dialect;

    use SQL::Dialects::Role;

    sub get_config {
        return <<CONFIG;
    [SECTION]
    item1

    [ANOTHER SECTION]
    item1
    item2
    CONFIG
    }

=head1 DESCRIPTION

This adds the role of being a SQL::Dialect to your class.

=head2 Requirements

You must implement...

=head3 get_config

    my $config = $class->get_config;

Returns information about the dialect in an INI-like format.

=head2 Implements

The role implements...

=head3 get_config_as_hash

    my $config = $class->get_config_as_hash;

Returns the data represented in get_config() as a hash ref.

Items will be upper-cased, sections will be lower-cased.

    {
        section => {
            ITEM1       => 1,
            ITEM2       => 2,
        },
        another_section => {
            ITEM1       => 1,
            ITEM2       => 2,
        }
   }
