 113 <ul>
 114     <li>The cross platform engine</li>
 115     <li>Platform code for Fonts, Painting, Networking, Events</li>

 144 <h1>Competition and Collaboration</h1>
 145 <ul>
 146     <li>WebCore/ is the actual rendering engine.</li>
 147     <li>WebKit/ is the API and where ports differentiate them.</li>
 148     <li>Ports should only compete on API and performance.</li>
 149     <li>Features might start in WebKit/ but move to WebCore.</li>
 150     <li>Examples include printing, event handling, ...</li>

 155 <h1>Printing example</h1>
 156 <ul>
 157     <li>Started in WebKit/win</li>
 158     <li>Alp made it general usable and put it into WebKit/gtk.</li>
 159     <li>Simon took the copy and put it into WebCore/platform.</li>
 160     <li>Other ports like Chromium can directly use it.</li>

 166 <ul>
 167     <li>Certain bugs are in port specific code?</li>
 168     <li>Ideally it would be automatically fixed in every port.</li>
 169     <li>In practice: Watch commits, get poked by port maintainers</li>
 170     <li>In practice: Kill duplication and share in WebCore/</li>
