 TODO NOW:
 
-- Fix mediawiki repository (has lots of stale files and a weird
-  history. This also means that the ichuang wiki will need to be
-  remigrated; frob .scripts-version to make it acceptable, but
-  otherwise should be fairly trivial).  When I say "fix", I mean
-  "redo". Thorough documentation would be good too.  Some bits
-  can be automated and/or have tools to assist it
 - Whiteboard the flow for performing an upgrade on a single
   install. How assisted does it need to be?
 - Conduct migration tool testing
 - Create mass-migration tool (should be able to limit on mediawiki)
 - Run parallel-find.pl
 - Migrate all mediawikis
+- Wordpress needs to have a .scripts/update script written for
+  its latest version
+
+NOTES:
+
+- A perfectly formed autoinstall with upgrade paths for all of
+  the intervening versions is not really feasible to implement.
+  As such, we want to migrate everything to -scripts, and then
+  generate a -scripts2 with the correct .scripts directory.
+  We will then nop update some installs, but this will prevent
+  us from having to migrate and update concurrently.
