nit: this comment is a bit verbose. can you shrink it down a bit?

also, the return type should be a "ui::Clipboard::SourceTag" (then you wouldn't
need to say that in the comment) so that it matches the cc file.

i.e. Returns a tag, for OffTheRecord contexts only, that identifies the contents
of the clipboard as such.

If I include clipboard.h, apps/app_restore_service.cc compilation breaks. This
is because a command doesn't include /usr/include/gtk-2.0 directory and gtk.h
can't be found. How should I circumvent that?

i'm not familiar with gtk. you can ask erg

The only thing I can think of is that you're doing a linux_aura build. We don't
put gtk in the build path in most of linux_aura except for the very small
coordined off library that can access it. (We don't use ClipboardGtk there,
either.)

Done.
