% Specify Runners
% ------- -------
%~ This command discards any current runner styles and sets up to use style
%~ *style1* on the current page, *style2* on the next, *style3* on the one after
%~ that, and so forth. The last style specified is used as the style for all
%~ subsequent pages (it becomes the default style). No spaces are allowed in the
%~ list.

\maplist{\gdef \zdefrun {##1}}{\zrunlist}%
\if \zoverrun \expandafter\overriderunners\expandafter{\zoverstyle}\fi

%~ This command overrides the style for the current page, using style *style*
%~ instead. After the current page, runner styles revert to those established
%~ by the last |\setrunners| command.
