Template:LocalizePrintf
This template returns a localized version of a "canned" phrase that we use in the interfaces. The phrase passed in is in English, but the output is in the language of the page that invokes it. Therefore if we call the template from
[[some page]], we'd get the English version of the page, but if we call it from [[some page/es]], we would get the Spanish version of the phrase.
Here is an example:

It is also possible to pass in numbered place-holders in the form of %n where n is a number between 1 and 9 (it stops at 9 because %1 will match %10 - maybe we could fix that, but we really shouldn't need that many place-holders). The arguments that follow will replace the placeholders:
