=head1 NAME

DBIx::Custom::MySQL - MySQL implementation

=head1 SYNOPSYS

    # Connect to the database

    my $dbi = DBIx::Custom::MySQL->connect(

        user     => 'taro', 

        password => 'kliej&@K',

        database => 'dbname'

    );

    # Get last insert id

    my $last_insert_id = $dbi->last_insert_id;

=head1 ATTRIBUTES

L<DBIx::Custom::MySQL> inherits all attributes from L<DBIx::Custom>

and implements the following new ones.

    $dbi     = $dbi->host('somehost');

Host name or IP address.

Port number.

C<connect()> method use this value to connect the database

if C<data_source> is not specified.
