=head1 DIRECTORY LAYOUT
-It's heavily based upon L<DBIx::Migration::Directories>.
+Arguably this is the best feature of L<DBIx::Class::DeploymentHandler>. It's
+heavily based upon L<DBIx::Migration::Directories>, but has some extensions and
+modifications, so even if you are familiar with it, please read this. I feel
+like the best way to describe the layout is with the following example:
+
+ $sql_migration_dir
+ |- SQLite
+ | |- down
+ | | `- 2-1
+ | | `- 001-auto.sql
+ | |- schema
+ | | `- 1
+ | | `- 001-auto.sql
+ | `- up
+ | |- 1-2
+ | | `- 001-auto.sql
+ | `- 2-3
+ | `- 001-auto.sql
+ |- _common
+ | |- down
+ | | `- 2-1
+ | | `- 002-remove-customers.pl
+ | `- up
+ | `- 1-2
+ | `- 002-generate-customers.pl
+ |- _generic
+ | |- down
+ | | `- 2-1
+ | | `- 001-auto.sql
+ | |- schema
+ | | `- 1
+ | | `- 001-auto.sql
+ | `- up
+ | `- 1-2
+ | |- 001-auto.sql
+ | `- 002-create-stored-procedures.sql
+ `- MySQL
+ |- down
+ | `- 2-1
+ | `- 001-auto.sql
+ |- preinstall
+ | `- 1
+ | |- 001-create_database.pl
+ | `- 002-create_users_and_permissions.pl
+ |- schema
+ | `- 1
+ | `- 001-auto.sql
+ `- up
+ `- 1-2
+ `- 001-auto.sql
+
+So basically, the code
+
+ $dm->deploy(1)
+
+on an C<SQLite> database that would simply run
+C<$sql_migration_dir/SQLite/schema/1/001-auto.sql>. Next,
+
+ $dm->upgrade_single_step([1,2])
+
+would run C<$sql_migration_dir/SQLite/up/1-2/001-auto.sql> followed by
+C<$sql_migration_dir/_common/up/1-2/002-generate-customers.pl>.
+
+Now, a C<.pl> file doesn't have to be in the C<_common> directory, but most of
+the time it probably should be, since perl scripts will mostly be database
+independent.
+
+C<_generic> exists for when you for some reason are sure that your SQL is
+generic enough to run on all databases. Good luck with that one.
+
+Note that unlike most steps in the process, C<preinstall> will not run SQL, as
+there may not even be an database at preinstall time. It will run perl scripts
+just like the other steps in the process, but nothing is passed to them.
+Until people have used this more it will remain freeform, but a recommended use
+of preinstall is to have it prompt for username and password, and then call the
+appropriate C<< CREATE DATABASE >> commands etc.
+
+=head1 PERL SCRIPTS
+
+A perl script for this tool is very simple. It merely needs to contain an
+anonymous sub that takes a L<DBIx::Class::Schema> as it's only argument.
+A very basic perl script might look like:
+
+ #!perl
+
+ use strict;
+ use warnings;
+
+ sub {
+ my $schema = shift;
+
+ $schema->resultset('Users')->create({
+ name => 'root',
+ password => 'root',
+ })
+ }
=attr schema
The L<DBIx::Class::Storage> that is I<actually> used to talk to the database
and generate the DDL. This is automatically created with L</_build_storage>.
-=attr sqltargs
+=attr sql_translator_args
-#rename
+The arguments that get passed to L<SQL::Translator> when it's used.
-=attr upgrade_directory
+=attr script_directory
-The directory (default C<'sql'>) that upgrades are stored in
+The directory (default C<'sql'>) that scripts are stored in
=attr databases
Set to true (which is the default) to wrap all upgrades and deploys in a single
transaction.
+=attr schema_version
+
+The version the schema on your harddrive is at. Defaults to
+C<< $self->schema->schema_version >>.
