SYNOPSIS

Basic usage:

#!/usr/bin/env perl
#
# dh.pl

use App::DH;
App::DH->new_with_options->run;

usage: dh.pl [-?cdfhIos] [long options...] (install|upgrade|write_ddl)
	-h -? --usage --help     Prints this usage information.
	-c --connection_name     either a valid DBI DSN or an alias
	                         configured by DBIx::Class::Schema::Config
	-f --force               forcefully replace existing DDLs. [DANGER]
	-s --schema              the class name of the schema to generate
	                         DDLs/deploy for
	-I --include             paths to load into @INC
	-o --script_dir          output path
	-d --database            database backends to generate DDLs for. See
	                         SQL::Translator::Producer::* for valid values

	commands:

	install                       install to the specified database connection
	upgrade                       upgrade the specified database connection
	write_ddl                     only write ddl files

If you don't like any of the defaults, you can subclass to override

use App::DH;
{
    package MyApp;
    use  Moose;
    extends 'App::DH';

    has '+connection_name' => ( default => sub { 'production' } );
    has '+schema'          => ( default => sub { 'MyApp::Schema' } );
    __PACKAGE__->meta->make_immutable;
}
MyApp->new_with_options->run;
