What do the Mircleman collections include?

[Spider-Chan]

Miracleman is my all time favorite comic book series, and I was overjoyed when Marvel announced they were finally reprinting it. I decided to hold on until a omnibus would be announced, because of course this deserves a omnibus collection.

However, years have passed and I don't see when a omnibus would be released. So I've decided to start with the collections they've released so far.

My question is, do the collections also include the backstories and all the extra content that were in the single issues? Like the Warpsmiths story.
