[vox-tech] Scheme question

[Brian Lavender]

I have been reading "Essentials of Programming Languages" and I came
across the following sample code. What does the backtick do?

brian

  ;; var-exp : Var -> Lc-exp
  (define var-exp
    (lambda (var)
      `(var-exp ,var))

"There are two ways of constructing a software design. One way is to
make it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies."
