Check if a .Lit ebook file has been DRMed

Question

Do we have any documentation that describes how to read the header information in Microsoft ebook format - ebook(dot)LIT .

We're trying to check if a bunch of ebooks have been protected by DRM. I'm assuming that there is a way to check a few attributes to ascertain that the file has been created with DRM levels 1-5.

Plan to discard the ebooks that have such DRM encodings.
