Hello again :)

I'm moving forward with my go library and I have arrived at the point where
I need to read the records from the
data pages.

>From what I understood by reading the source code of libmdb, all the
secrets are contained in the MSysObjects table.

Is there a good reference or description of the MSysObjects table and
object ? What is the basic approach ?
