Apps to help you see what's going on when you run Celerity tests. There are more READMEs further down the tree:
The applications set up a TCP server on port 6429. Celerity will look for anyone listening on this port whenever an instance of the browser is created, and, if found, send HTML dumps whenever a page is changed using the protocol described on this page on the Celerity wiki.
The RubyCocoa and Qt apps has the WebKit inspector enabled - right-click and Inspect Element. The SWT version includes the MouseOver DOM inspector.
Note: The pure Cocoa version in the repository is not working yet, use Qt or RubyCocoa for now.
