Sub Articulo 48.0

 I'd like to use the $Id$ string produced by rcs in one of the title
 arguments of a document to help track versioning. However, you can't use
 \verb or the verbatim enviroment in the argument of any commands. Any
 suggestions?
Should you use plain TeX, you might want to look at the following code, which
sets the \footline in my diploma thesis:
\begingroup
   \catcode`\$ = 12
   \catcode`\_ = 12
   \frenchspacing
   \global\footline = {%
      \iftitle
         \global\titlefalse
         \hss\headlinesf\folio
      \fi
      \ifproofmode
         \font\seventt = cmtt7
         \seventt
         \hss
         \frenchspacing

         \hss
      \else
         \hfil
      \fi
   }%
