         my $admin = DBIx::Class::Admin->new(
           schema_class=> 'MY::Schema',
           sql_dir=> $sql_dir,
           connect_info => { dsn => $dsn, user => $user, password => $pass },
         );

         # create SQLite sql
         $admin->create('SQLite');

         # create SQL diff for an upgrade
         $admin->create('SQLite', {} , "1.0");

         # upgrade a database

ATTRIBUTES

   schema_class
       the class of the schema to load

   schema
       A pre-connected schema object can be provided for manipulation

   resultset
       a resultset from the schema to operate on

   where
       a hash ref or json string to be used for identifying data to manipulate

   set
       a hash ref or json string to be used for inserting or updating data

       config_stanze should also be provided to locate where the connect_info is in the config
       The config file should be in a format readable by Config::Any.

   config_stanza

       information designed for use with catalyst config files

   config
       Instead of loading from a file the configuration can be provided directly as a hash ref.
       Please note config_stanza will still be required.

   version
       Used for install, the version which will be 'installed' in the schema

   preversion

METHODS

   create
       Arguments: $sqlt_type, \%sqlt_args, $preversion

       "create" will generate sql for the supplied schema_class in sql_dir. The flavour of sql to
       generate can be controlled by supplying a sqlt_type which should be a SQL::Translator
       name.

       Arguments for SQL::Translator can be supplied in the sqlt_args hashref.

       Optional preversion can be supplied to generate a diff to be used by upgrade.

   upgrade
       Arguments: <none>

       upgrade will attempt to upgrade the connected database to the same version as the
       schema_class.  MAKE SURE YOU BACKUP YOUR DB FIRST

   install
       Arguments: $version

       install is here to help when you want to move to DBIx::Class::Schema::Versioned and have
       an existing database.  install will take a version and add the version tracking tables and
       'install' the version.  No further ddl modification takes place.  Setting the force
       attribute to a true value will allow overriding of already versioned databases.

   deploy
       Arguments: $args

       deploy will create the schema at the connected database.  $args are passed straight to
       "deploy" in DBIx::Class::Schema.

   insert
       Arguments: $rs, $set

       insert takes the name of a resultset from the schema_class and a hashref of data to insert
       into that resultset

   update
       Arguments: $rs, $set, $where

       update takes the name of a resultset from the schema_class, a hashref of data to update
       and a where hash used to form the search for the rows to update.

   delete
       Arguments: $rs, $where, $attrs

       delete takes the name of a resultset from the schema_class, a where hashref and a attrs to
       pass to ->search.  The found data is deleted and cannot be recovered.

   select
       Arguments: $rs, $where, $attrs

       select takes the name of a resultset from the schema_class, a where hashref and a attrs to
       pass to ->search.  The found data is returned in a array ref where the first row will be
       the columns list.
