=head1 NAME

Module::Install::DBICx::AutoDoc - Use your Makefile to run DBICx::AutoDoc

=head1 VERSION

Version 0.03

=head1 SYNOPSIS

In MakeFile.PL:
	
	dbicx_autodoc('doc'); # use name() or module_name() as Schema package
	# or
	dbicx_autodoc('doc','My::Schema'); # better be in lib/
	# or
	dbicx_autodoc({
		output => 'doc',
		schema => 'My::Schema'
	});

From CLI:
	
	make autodoc

=head1 METHODS

=head2 dbicx_autodoc

Add a DBICx::AutoDoc call to a Makefile

Example (in Makefile.PL):
	
	name 'My-Schema';
	all_from 'lib/My/Schema.pm';
	author 'Foo Bar';
	
	dbicx_autodoc('doc'); # use name() or module_name() as Schema package
	# or
	dbix_autodoc('doc','My::Schema'); # better be in lib/
	# or
	dbix_autodoc({
		output => 'doc',
		schema => 'My::Schema'
	});
	
This would run DBICx::AutoDoc for My::Schema and store documents in <module-directory>/doc.

=head1 BUGS

B<Warning!>, I have yet to write a "proper" unit test for the Makefile preamble output. I do use this module for my internal db libs and haven't found a problem yet. If someone wanted to contribute a good unit test it would be greatly appreciated. 

Please report any bugs or feature requests to C<bug-module-install-dbicx-autodoc at rt.cpan.org>, or through
the web interface at L<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Module-Install-DBICx-AutoDoc>.  I will be notified, and then you'll
automatically be notified of progress on your bug as I make changes.
