get_appeal

Includes the best localised appeal subpage of Template:Appeal, based on appeal name, language, and country given. Also passes the parameters to the selected appeal template for their use (e.g. in localising amounts with {{AppealAmountSwitch}})

Parameters:

appeal - initial "Appeal-" (which was required for older links) is stripped off if present
language
country
Any other parameters to pass through to the appeal template (e.g. sitename)

Example:

{{#invoke:Main|get_appeal|appeal=Alan|country=CA|language=fr}}

Display Template:Appeal/Alan/fr/CA if it exists, else
display Template:Appeal/Alan/fr if it exists, else
display Template:Appeal/Alan/en if it exists, else
display Template:Appeal/default/fr if it exists, else
display Template:Appeal/default/en

Replaces {{2012FR/Switch/Appeal}}

get_infobox

Does basically the same thing for subpages of Template:Infobox

Replaces {{2012FR/Switch/Infobox}}

get_tax_message

Code should be fairly self explanatory. Allows overriding the default message for certain countries.

page_language

Return the language code of the current subpage. If it isn't a subpage, or isn't a valid language code, return 'en'.
