maybe this link may help?
http://live.gnome.org/GnomeShell#GNOME_Shell:
Technology
 "Much of the code of the shell is written in Javascript but uses 
Clutter and GNOME platform libraries via GObject Introspection 
<http://live.gnome.org/GObjectIntrospection> and JavaScript bindings for 
GNOME <http://live.gnome.org/Gjs>. ...."

Note: to get USB to mount in Sugar-Emulator in VirtualBox4.0.4
Insert USB you want to use
Start VirtualBox
Settings/Ports/USB
on right side click on usb icon (+)
select the USB you have mounted

MUST BE DONE: on desktop safely remove USB
start your VirtualBox appliance
insert the USB again
click on journal in f3 of sugar
USB will now appear in bottom corner of sugar-emulator when frame retracts
click on USB and contents will be listed
drag-drop content (.xo) from usb to journal icon on bottom left.

This is not obvious....that usb has to be removed and reinserted.

This assumes that the extensions are installed (for USB 2 support)
http://download.virtualbox.org/virtualbox/4.0.4/Oracle_VM_VirtualBox_Extension_Pack-4.0.4-70112.vbox-extpack
(These are not GPL- for private use only license)
(To install: click on downloaded extensions from desktop or where it 
downloaded)
