Maybe I did not deny this explicitly enough previously, while I wrote that 
the `arcs' package heavily uses LaTeX's font selection scheme. But I thought 
that NFSS can be loaded with plain TeX. More about something like this:

    http://www.tex.ac.uk/FAQ-fonts-pln.html

which is too much for me. Still, you could not directly use the `arcs'
package, it has LaTeX commands like \newcommand and \symbol, and it 
needs the `relsize' package which has commands like \DeclareRobustCommand. 
Well, maybe after

    \def\newcommand#1[1]{\def#1}

and \DeclareRobustCommand likewise -- and \def\symbol#1{\char#1} ...
you can load arcs.sty. For me it is not obvious.

\bye,

    Uwe.
