+_What else?_
+
+== Thoughts ==
+
+Transitioning from wc-1 to wc-ng is made very difficult by the fact
+that a ton of code is aware of the "stub" in the parent dirctory
+containing some information subdirectories. Most important is the
+"deleted" flag (not explained here). The separation of state between
+the stub entry in the parent, and the "full" entry in the subdir
+itself is seen throughout the code. Finding a proper abstraction
+for this to ease the transition will be very important.
+
+Another consideration is the "schedule" concept. wc-ng uses very
+different ideas ("presence" is the key state, and then "status" is
+derived from that). These are not one-to-one mappings, so it is
+not a simple code transformation to switch to wc-ng.
