+   Shows the last modification date of the specified page, or the page the
+   macro appears in if not specified. An optional argument,  delta, can be
+   given to show the time elapsed since the last modification. The output is
+   placed in span with a title that gives the exact modification date and
+   the author of the change.  This span can be optionally CSS styled to have
+   a thin grey line under the text and a help cursor that tooltips the
+   span title.
+
+   For example, ![[LastModified(WikiStart)]] produces:
+      [[LastModified(WikiStart)]]
+
