commit aec5a1ffabefb1a81fb5c6e4ad095637aaa563c8
Author: Ben Kaduk <kaduk@mit.edu>

    Document the prdb (ubik) file format
    
    Briefly cover the ubik header and mention that it is not part of the
    logical database (since it is just used for the consistency procedure).
    
    Describe the fields of the prheader and how they are used.  Mention that
    all subsequent entries are blocks of the same size, whose type can be
    distinguished by a shared flags field.  User and group entries are similar,
    and supergroup entries are described as a diff from regular group entries,
    as only a handful of fields change.  Continuation entries can be used
    for user, regular group, or supergroup entries.
    
    Call out what fields are invariant within which classes of entry, so that
    these properties can be preserved (or knowingly eliminated) for future
    extensions to the format.
