-This class is the meat of L<DBIx::Class::DeploymentHandler>. It takes care of
-generating sql files representing schemata as well as sql files to move from
-one version of a schema to the rest. One of the hallmark features of this
-class is that it allows for multiple sql files for deploy and upgrade, allowing
-developers to fine tune deployment. In addition it also allows for perl files
-to be run at any stage of the process.

on an C<SQLite> database that would simply run
-C<$sql_migration_dir/SQLite/schema/1/001-auto.sql>. Next,
+C<$sql_migration_dir/SQLite/schema/1/001-auto.sql-json>. Next,
$dm->upgrade_single_step([1,2])
-would run C<$sql_migration_dir/SQLite/up/1-2/001-auto.sql> followed by
+would run C<$sql_migration_dir/SQLite/up/1-2/001-auto.sql-json> followed by
C<$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

+C<.pl> files don't have to be in the C<_common> directory, but most of the time
+they should be, because perl scripts are generally 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.
of preinstall is to have it prompt for username and password, and then call the
appropriate C<< CREATE DATABASE >> commands etc.
+=head1 SERIALIZED SQL
+
+The SQL that this module generates and uses is serialized into an array of
+SQL statements. The reason being that some databases handle multiple
+statements in a single execution differently. Generally you do not need to
+worry about this as these are scripts generated for you. If you find that
+you are editing them on a regular basis something is wrong and you either need
+to submit a bug or consider writing extra serialized SQL or Perl scripts to run
+before or after the automatically generated script.
+
+B<NOTE:> Currently the SQL is serialized into JSON. I am willing to merge in
+patches that will allow more serialization formats if you want that feature,
+but if you do send me a patch for that realize that I do not want to add YAML
+support or whatever, I would rather add a generic method of adding any
+serialization format.
