There is a 3rd option and probably others too
3. Just leave it to the disclaimer to explain why the icons look different
and perhaps signpost people to how to change sets for themselves and a place
to find new sets.
That's what it says now in the Prefaces that have been revised. (All
will be revised for v4.)
4. In the disclaimer print 1 copy of the Tango set and 1 of the Galaxy set
so that people can refer back to it if they have problem with a screen-shot
Tom, that would be a LOT of icons. Pages and pages of them. Not
practical at all.
