This is very useful plugin for those who want manage multiple complex meta fields easily. Imagine you have Companies post type and you need to assign multiple Employees to these Companies somehow without creating new post type for them. Employees can contain different fields as well.

After you setup all your custom fields for existing post types on a Settings page you will be able to add as many custom fields to the post as you need by clicking "Add New" button.

There are some handy functions that help getting access to custom fields on front-end the way similar to standard post loop. See "Functions" below.
