Template:Newsarchive/doc

Template which produces a small box with links to news archive categories up to 5 years back from a given year. If no year is given, it starts with the current.

Uses newsarchive/aux.

Technical
This template uses the parser function  which is considered an "expensive parser function", only a limited number of which can be included on any one page (including functions inside transcluded templates). When this limit is exceeded, any further  functions automatically return false, whether the target page exists or not.

As such, this template should not be expanded to check for more than 6 years. 99 is the default value for expensive parser functions per page; this template uses up to 13 ifexist calls per year, making 7 the theoretical maximum of years. A little "buffer" should be given, hence 6 years maximum.
