[ARC5] POT: Re: ARC-5 AC Power Supply solutions

[J. Forster]

Some standardization is a good thing, IMO, but the recent breeds of
Eurocrats have taken it to ridiculopus extremes. viz. RoHS.

It's a manifestation of the unchecked growth of Eurosocialism. Sadly, some
US politicians envy those trends and seem bent on importing them along
with Belgian Endive, snails, Brie, and Perrier.

In some ways you have to admire them though. They have made extremely well
paid, cushy, secure jobs out of nothing.

YMMV,
