+  Hubbub
+--------
+
+  NetSurf can use Hubbub, the project's HTML parser, instead of using libxml2's
+  HTML parser.  To build this, you will also require libparserutils.  Firstly,
+  check out libparserutils from;
+  
+      svn://svn.netsurf-browser.org/trunk/libparserutils
+  
+  and do the usual "sudo make install".  Once this is built and installed, you
+  can check out and build Hubbub.  Check out hubbub from;
+  
+      svn://svn.netsurf-browser.org/trunk/hubbub
+
+  and again do the usual "sudo make install".
