    - Reliability: The NT Configuration Manager offers a variety of complex
                algorithms which continously check the state of a loaded hive or
                a hive that is being loaded, as well as per-key node damage.
                Furthermore, upon detection of a damaged node, the Configuration
                Manager is often able to repair the Registry and bring it back
                to a usable state, through a process called self healing.

    - Object-Oriented: Like many other core structures in NT, the Configuration

+**As of 11/5/2007
+  Significant parts of the rewrite have been merged in and bugfixed with
+  existing cm code into the main tree, in the /config directory.
+  ~100% of the Initialization code is now complete, including reading the
+  System Control Vector.
+  ~80% of the ARC Hardware Configuration Node/Tree code has been written.
+  It has been decided to stick with internal NT names since this simplifies

   TODOs:
-    Complete KCB implementation with CmpEnlistKeyWithKcb.
-    Re-write some parts of CmInitSystem1 to handle NTLDR-style Hardware Hive.
-    The idea is that, by the time this branch is ready, this will be compatible
-    with ROS. Otherwise, I'll work with Hervé, Filip and Aleksey to make it happen.
+    Write Driver-list APIs directly into main branch since they should be low-
+    level enough to bypass the Object Manager interface (just like the System
+    Vector code).
+    Fix Cm Wrapper routines to read/write in chunks of 64K to avoid issues when
+    working with a large set of data (this is what NT does as well).
+    Try to make more code in trunk to use CmpOpenHiveFiles instead of the code
+    being used now.
+    Modify FreeLDR to actually send an ARC Configuration Root Tree instead of
+    writing to the hardware hive itself.
+    Once the above is done, modify current hacks to handle proper hardware hive
+    creation and initialization.
+    Once the above is done, merge trunk back into the Cm Rewrite branch, and
+    resume work on rewrite when will/time is available.
