+Caveats
+=======
+
+File Upload
+-----------
+
+Windmill can't do file uploads. This is a limitation of browser Javascript
+support / sandboxing, not of Windmill per se.  It would be nice if there were
+some command that would prime the Windmill HTTP proxy to add a particular file
+to the next HTTP request that comes through, so that uploads could at least be
+faked.
