Repair bitrot in the utils/apidoc/mdn/ code. It now runs all the way through,

utils/apidoc/mdn/README.txt

+***** Current status
+
+Currently it runs all the way through, but the database.json has all
+members[] lists empty.  Most entries are skipped for "Suspect title";
+some have ".pageText not found".
+
+Currently only works on Linux; OS X (or other) will need minor path changes.
+
+You will need a reasonably modern node.js installed.
+0.5.9 is too old; 0.8.8 is not too old.
+
+I needed to add my own "DumpRenderTree_resources/missingImage.gif",
+for some reason.
+
+***** Overview
+
 Here's a rough walkthrough of how this works. The ultimate output file is
 database.filtered.json.
 
 full_run.sh executes all of the scripts in the correct order.
 
 search.js
 - read data/domTypes.json
 - for each dom type:
   - search for page on www.googleapis.com
   - write search results to output/search/<type>.json
@@ skipping 29 matching lines @@
 - xhr output/extract/<type><index>.html.json
 - all sorts of shenanigans to actually pull the content out of the html
 - build a JSON object with the results
 - do a postmessage with that object so extractRunner.js can pull it out
 
 - run postProcess.dart
   - go through the results for each type looking for the best match
   - write output/database.html
   - write output/examples.html
   - write output/obsolete.html
-  - write output/database.filtered.json which is the best matches
+  - write output/database.filtered.json which is the best matches
+
+***** Process for updating database.json using these scripts.

+TODO(eub) when I get the scripts to work all the way through.
