/**
* to benefit of [[:Template:Multilingual description]]
*
* Implements language selection for multilingual elements
*
* WARNING: DON'T RELY ON COMMONS-STUFF. THIS SCRIPT IS FOREIGN-USED
* THE SCRIPT IS ALSO USED BY SOME GADGETS THAT LOAD CONTENT DYNAMICALLY
*
* In certain environments, it's not feasible to neatly box away each
* different language into its own section of the site. By marking elements
* multilingual, you can emulate this behavior by only displaying the
* message in the user's language. This reduces the "Tower of Babel" effect.
