Description
You may notice there are a lot of plugins that do almost the same things as this one. But there always is a small difference.
In current case plugin allows to add REPEATABLE field sets for any Post Type. Meaning you can add any amount of the same field sets to a post or page while editing it.
Then you can output them in a post loop using built-in API.
Moreover, it is light, simple and useful in the same time.
