Using troff and eqn from DWB 2.0, I'd like to be able to draw a slanted 
line through various terms in an equation, to indicate that those terms
are being neglected in an analysis.  The endpoints of each line to be 
drawn should be the lower-left and upper-right corners of a box 
surrounding the relevant term in the equation.  Does anyone have any 
ideas on the best way to do this?

I know about pic, although I've never used it.  Can pic be used inside
eqn delimiters?  If so, how can I mark the endpoints of the line to be 
drawn?
