On our site we use Easy Digital Downloads. Once an EDD download (e-commerce product) definition has been created it is usually supported by
other posts that provide additional information – help or tutorial information for example. Ideally, these posts will have a similar style,
use similar words and need to reference the same core information about the download such a the current version number, the slug, the excerpt, etc..
One way is to cut-and-past information from a download in to each post. But this means that when download details change, its essential to
remember to update any related posts. This plugin provides another way: a set of plugins that allow you to reference details from a download
and in this way remove the need to update related posts.
