  @end defun
  
+ @defun copy-tree tree &optional vecp
+ This function returns a copy the tree @code{tree}.  If @var{tree} is a
+ cons cell, this makes a new cons cell with the same @sc{car} and
+ @sc{cdr}, then recursively copies the @sc{car} and @sc{cdr} in the
+ same way.
+ 
+ Normally, when @var{tree} is anything other than a cons cell,
+ @code{copy-tree} simply returns @var{tree}.  However, if @var{vecp} is
+ address@hidden, it copies vectors too (and operates recursively on
+ their elements).

  @defun number-sequence from to &optional separation
  This returns a list of numbers starting with @var{from}
  and incrementing by @var{separation} (or by 1 if @var{separation}
