VersionMenu is a tool to switch between different versions of a
page. A menu of the different versions is shown, with the current
version unlinked. Select any other version to switch to that
version. For example:
English | FranÃ§ais | EspaÃ±ol
As this example indicates, versions are typically used to provide the
same content in multiple languages. VersionMenu only shows those
versions that are available for the current page. If incomplete
translations exist, then only the supported languages are shown.
Versions are also used to manage any alternative presentation of the
same content, even if the language is the same. For example, you
might maintain two alternative versions of your pages for viewers with
different degrees of internet connectivity:
Normal version | Low-bandwidth version
Presumably the low-bandwidth version would use different templates, and fewer or smaller images.
