Using DJGPP (but not Allegro) is there a simple way to add an arbitrary chunk
of binary data after the DJGPP exe, and have it available for read/write as if
it were a file? Is there some sort of pointer in the exe to the end to allow a
simple seek to the start of the added data (if any) and read/write data there?

I know the obvious way to put stuff there: open the exe for binary output, seek
to the end of file and append. How the devil is this stuff found later though
for reading/modifying? By terminating the addendum with an offset back?
or.....?
