From 10715bbea71ffe5ee4b17558e0c108eb1a2a0021 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Modified to add an optional parameter to writeProperties to
 allow *all* properties to be written, rather than just the ones flagged as
 archivable.  Tony Peden requested this feature to make it easier for people
 to document properties.
