GNOME has documentations *without* a license.
While surfing through the 'Help Documents' (Main menu > Accessories > Help. Click on Go > All Documents) I came across *TWO* documentations which do *NOT* have a license.
Those documents, void of any licenses are:-
[1] Disk Usage Analyzer.
[2] GNOME Desktop System Administration Guide.
Is this a *BUG*?
