Thanks.  I don't see your name in copyright.list.  Did you sign the
copyright paperwork yet?  If not, then please fill the form below and
email it as instructed so the FSF can send you the relevant paperwork
to sign.

Can you figure out who are the authors of that file, so we can get their
copyright cleared?

Is it the "clipboard" or the "selection"?

Please don't change interprogram-cut-function, since this breaks down if
you use a single Emacs session with both GUI and text frames (and with
potentially various different terminal kinds).

Instead use gui-method-declare for gui-set-selection (new in Emacs-25).

Also, do I understand it correctly, that this only handles transfers in
one direction (i.e. pushing Emacs's selection to the X server, but not
fetching the X server's selection for use in Emacs)?
