Look at the help for the backquote function.

Basically, it's a macro which lets you have a quoted expression, but
it lets you selectively insert non-quoted values/results as well.  It
also has the handy ,@ splice operator which inserts the contents of an
array as individual items.

(let ((foo '(a b c d e))
      (one 1)
      (two 2)
      (three 3))
  `(,one ,two ,three four five ,@foo))

=> (1 2 3 four five a b c d e)

Get it?
