To me, explainations about the code belong in the code. When reading
some code I don't know about, I appreciate explainations located right
besides the code I'm trying to understand. I usually don't remember to
look into gdbint or any other document, and besides, it's incovenient
to have to search it, to see if there would be any additional info
there.

If I had to make a suggestion, I would embed all the information from
gdbint inside the code, and make gdbint a document generated from the
code.
