Module:Sandbox/Wnt/TextMarkup explained

---- This module accepts a piece of text or the name of a page ---- It acts on angle-bracket tags in the text to simulate an extension of the html/wiki markup set ---- Vaguely per, the tag is the first example, replaced with a number ---- that increases each count. You can set or reset the count and rate at any time by ---- where i=the number of that tag and j is the difference to succeeding tags.
