 ZConfig package.
 
 zconfig-brace-syntax
+    NOT ACTIVE
     An example of an alternate syntax for ZConfig.  This syntax was
     developed while trying the package initially, but was rejected.
     It is saved on a branch to avoid losing historical information.
 
 zconfig-schema-devel-branch
+    NOT ACTIVE
     Development branch for schema support in ZConfig.  The branch is
     based on the ZConfig trunk, but the development is strongly based
     on the work Chris McDonough started in the chrism-install-branch
-    for Zope 2.
+    for Zope 2.  This was merged into the trunk on 3-Jan-2002.
