[tex-eplain] sections and letterspacing

[Adam Fenn]

I have a section macro which  produces two centred lines but I would 
like to have these letter spaced using the \so{stuff} command from 
soul.sty.
Is this possible?

\input eplain
\input soul.sty

\def\section{%
  \vfill\supereject       		
               \begingroup
               \begingroup\center\Section}
               \def\Section#1{\uppercase{#1}\endgroup
               \endgroup
               }

  \section{A Very long section title that needs to be
               letter spaced and spread across two lines}

TIA
Adam.
