GPL 2(c) is the obnoxious banner clause that says that if you
take a random piece of non-interactive GPL code and incorporate
it in an interactive program, then that program must include a
startup banner telling the users that this is Free Software
under the GPL.

Similarly, cl-typesetting #5, says that if you incorporate
cl-typesetting in a larger program then that program (not its
output) must display a cl-typesetting banner in its primary
startup screen.

GPL 2(c) presumes a command-like program similar to
gdb/bash/emacs in its example text, cl-typesetting#5 presumes a
HTML-based user interface such as a cgi/php/jsp frontend.

So one must look very carefully to determine what places GPL
2(c) just within the DFSG (other than DFSG#10), and what causes
cl-typesetting #5 to be within or outside the DFSG.

This message is hastily written, please ignore any unpleasant wordings,
do not consider it a binding commitment, even if its phrasing may
indicate so. Its contents may be deliberately or accidentally untrue.
Trademarks and other things belong to their owners, if any.
