---
--- This module renders the {{Version}} template.
--- https://hoodedhorse.com/wiki/Against_the_Storm/Template:Version
---
--- This template #invokes VersionMessageBox.checkVersion(frame), below.
---
--- The template requires one argument provided by wiki page writers using the
--- template, which is the version of the game when the wiki page was last
--- updated. There is a second argument provided by the template itself that the
--- page writers canont overwrite, which always refers to the current version of
--- the game. The current version is identified by the wiki as
--- {{CurrentVersion}}.
---
--- Depending on the arguments, this module creates a message box that displays
--- when a reader opens a page that hasn't been reviewed and updated since the
--- version changed. The message box tells the reader what version of the game
--- the page was udpated with, the current version, and an encouraging note to
--- help keep the wiki up to date.
--- @module VersionMessageBox
