Manifest files - why and how?

[Egil]

When making a copy of the cp_demo.eba file ( found in the projects diretory ) and renaming it to avoid destroying the original, I noticed that the visual appearance of the Calendar Control demo changed. By also making a renamed copy of the cp_demo manifest file, things went back to normal.

Can anyone give a short and simple explanation on how such manifest files are used?

I think this is the best on source light weight explanation:

Thank you very much!
Just what I need. I searched the MSDN, but I must have used wrong keywords, as I didn't fin this reference.
