Can anybody enlighten me and get me back to the right way?

I feel some satanic forces making me believe that it is silly and stupid 
to have a copyright and a license (other than public domain) on files 
that contain trivial source code. for example, I would laugh at the 
following:

/* foo blah blah
  * copyright the LAUGHAFBLE group
  * license stuff: you should, you may, you must, ....
  * blah blah ..
  * yet again
  * once more
  */
void
assign(int x, int y)
{
  x = y;
  return;
}

but I have hope for an exorcise.

Isn't it far better to have a "trace" comment such as:
	/* written for NetBSD on Feb 31 1984 */
?
[at least, this saves a lot of tree when you a2ps|lpr]
