Manual redundant to project READMEs?

[chrisohaver]

IMO, we don't need a separately authored/maintained manual.

If the project READMEs are lacking in areas, we should improve them there.
For example, I think we could expand/improve the main project readme with better documentation of the Corefile format.

If we want to have a separate manual "package", we should build out READMEs such that they can be compiled automatically into a portable manual ... But as a separately authored/manually maintained set of documents it creates a lot more busy work to author and maintain, essentially two sets of documentation.
