% RUNNING HEADLINES (and footlines) with page numbers
%
% This is an alternative definition of \makeheadline, which can be
% used to put the running headlines in the right position. A new dimension
% called \headlineoffset specifies how much the headline is to be RAISED.
% The default, which is zero, puts the headline in the "usual" place.
% Similarly, \footlineoffset LOWERS the footline an extra bit. To meet
% the Yale Graduate School guidelines I used \headlineoffset=0.2in.
%
% This file is a part of TeXsis.

% \Headline and \Footline actually create the running head and foot
% lines. We make \the\headline=\HeadLine and \the\footline=\FootLine. For
% the first page of a chapter there is no headline, and no page number. For
% subsequent pages there is a running head line with page number, and nothing
% at the bottom of the page. The text of the running head and foot lines is
% kept in \HeadText and \FootText. \chapter and \section make their arguments
% the running head text, but you can change this by re-defining \HeadText
% immediately after calling these macros. By default the headline is written
% in italics; you can change this yourself in \HeadText.
%-%\headline={\HeadLine} % headline executes \HeadLine
% \HeadLine uses marks to turn off headline on first pages. \HeadText
% contains the text; \He@dText is set to it or \relax depending on
% \ifRunningHeads.
