% (because there is no command with parameter), but violates kerning
% in \CS-fonts. The new version defines |\uv| as command with one
% parameter and its properties are the exact opposite of the old
% version -- |\verb| not, kerning yes. The new version is the default in
% \LaTeXe\ (where it can be overrided by the |olduv| option).
% In plain \TeX\ and in \LaTeX\,2.09 compatibility mode, the old
% version is default, for backward compatibility (current csplain
