Now 

(define-record-procedures-parametric pare pare-of
  make-pare pare?
  (pare-one pare-two))

instead of the old

(define-record-procedures-parametric (pare a b)
  make-pare pare?

4288c6c2c7 The Scribble reader was improved to make it pull out the syntax 
punctuations outside of the form, as it does with quote punctuations.
So things like this

  #, @foo{...}

that required the space to make the @foo read as a scribble form are
now better written as

  @#,foo{...}

This changes all such occurrences.  (In case you see this change in
your files and are worried that there might be changes: I mechanically
verified that the result of `read'ing the modified files is identical
to the previous version.)

removed htdp-lang dependency on debugger
  removed deinprogramm dependency on stepper, debugger, and htdp-langs
