I just took a quick look, and it all still looks pretty
relevant to me.
The exact way the bytes are arranged to form row-records
has changed (to accommodate manifest types), the database
header is different and some of the "b trees" are now "b+ trees".
And the root-page of the sqlite_master table is now on page 1
(with the header) instead of 2. But these are all really
just details, the basic approach is the same.
If you need the precise details, it might be easiest to read
that document and then proceed to the comments in btreeInt.h.
