[Plugin: WordPress SEO by Yoast] Compatibility in case the plugin is not installed

Hi there, great fan of your plugin, I’m building a couple of themes which I would like to have some sort of fallback in case the user doesn’t have your plugin installed.

Is there for example a functions like yoast_breadcrumb for the title, meta tags, etc?

thanks mate keep up the nice work.
