To build and run these examples using WebKitGTK+ then do the following
sudo apt-get install libwebkitgtk-3.0-dev
mkdir vendor
cd vendor
darcs get --lazy http://patch-tag.com/r/hamish/gtk2hs
cabal install ./gtk2hs/tools
cd ..
cabal install cabal-meta cabal-src
cabal-meta install -fgtk3 --force-reinstalls
Due to an issue with gtk2hsC2hs you may have to run that last step twice. You may also need to add -fwebkit1-8 if you have an older version of webkit.
Once this is done you should run the examples with ghcjs-hello freecell multiple-pages [URL to share/multiple-pages-0.0.1/index.html]
Installing WebKitGTK+ is not well supported on OS X and Windows, so we strongly recommend using Linux (or a Linux VM).
