[Zope] Question of ZPL etiquette

[David Pratt]

Hi Andreas. I had interpreted that the header information was satisfying 
the requirement to identify changes for

5. If any files are modified, you must cause the modified files to carry 
prominent notices stating that you changed the files and the date of any 
change.

Since I am under version control and date is in $Id$, I was just going 
to indicate a statement "Modified ZPL 2.1(5) code" under my $Id$ then 
use my own header with reference to the LICENSE.txt Would you say this 
is a reasonable way to go? Many thanks.

Regards,
David
