BUILDING_FOR_TITANIUM

------------------------OS X--------------------------
WebKit must be built against the 10.5 SDK and i386 and ppc architectures.
This is what a typical build command might look like:
./WebKitTools/Scripts/build-webkit --release \
  SDKROOT=/Developer/SDKs/MacOSX10.5.sdk MACOSX_DEPLOYMENT_TARGET=10.5 \
  WEBKIT_SYSTEM_INTERFACE_LIBRARY=WebKitSystemInterfaceLeopard \
  ARCHS="i386 ppc" ONLY_ACTIVE_ARCH=NO

------------------------Win32-------------------------
./WebKitTools/Scripts/build-webkit --release --cairo-win32

------------------------Linux-------------------------
./WebKitTools/Scripts/build-webkit --gtk
