I would like to "dynamically generate" values for the following 3 hard-coded
properties based on a rule, and the current default paper size, but I dont
know scheme:

paper-height = 11.0\in
paper-width = 8.5\in
line-width = 7.7\in

So basically how would I code the above hard coded values to be math
expressions based on the following rule:

I always want my left and right margins to be .4 inches.

So the formula for line with would be (default paper width - .8)

The formula for paper-height and paper-width would be whatever the default
paper currently is, but I dont know how to set it from those values.


this is possible in CVS by doing

\paper {
right-margin = #(* 5 cm)
left-margin = #(*  5 cm)
#(set-paper-size "a4")
}
