As well as the <code>main</code> function, this module has separate functions for each box type. They are accessed using the code <code><nowiki>{{#invoke:Message box|mbox|...}}</nowiki></code>, <code><nowiki>{{#invoke:Message box|ambox|...}}</nowiki></code>, etc. These will work when called from other modules, but they access code used to process arguments passed from #invoke, and so calling them will be less efficientwillt than calling <code>main</code>.
