My question is this: how can I add the co-called "running" title and author name on the top of each page? This feature is often used in journals so that the short running title is shown on the top of odd pages and the running author name is shown on the even pages.
In journal style files they usually provice the
\authorrunning commands to do it quickly, but how can I add them myself?
And also it would be very good (almost necessary) to add a line separating this running title of the rest of a page.
