Compare the RI files under .../share/ri/3.3.0/system/ with the corresponding output expected under .../share/doc/ruby/html/. Start with the listed DidYouMean, Net, Object, URI, and WIN32OLE paths and trace how their HTML files are generated. Done means the eleven listed HTML files are produced for the matching RI entries.
