The Code Snippet plugin declares as dependencies the following plugins : Widget, Dialog.
The Widget plugin declares as dependencies the following plugins : Line Utilities, Clipboard.
I've included all of them in the above installation procedure : I do not know if the "main" Code Snippet plugin really needs them or not.
