You'll need to grab a style file out of the consult locker.  To do this,
go to your thesis directory and type:

	attach consult
	cp /mit/consult/lib/tex/macros/reader.sty .

	(Don't forget the . at the end)

Then in  main.tex,  add the line

     \usepackage{reader}

after your \documentclass line

In cover.tex, after the \supervisor command, insert a \reader command.
It's just like the \supervisor command: \reader{name}{title}
 
If you have a second reader, just use a second \reader command.
