  The  files  here  are  a  quick-and-dirty,  incomplete,  and  crude,
overview, provided by the  original author and umhampered with, except
for this note.   If you need better information, try to  get a hang of
the  code in  src/_pristine/emu.c.   It  is not  easy  because of  the
strange coding  style, but  goes a lot  deeper than  the documentation
here.  Don't get lost within it, and don't get frustrated.
