-- Below these comments: Internationalization table
-- How to translate this module (for languages without variants):
-- • Characters inside single and double quotation marks are called strings.
-- The strings in this i18n table are used as output.
-- • Strings within square brackets are keys.
-- • Strings are concatenated (joined) with two dots.
-- • Set the string after «local lang =» to your language's code.
-- Change the first key after "i18n" (usually "en-GB") to the same thing.
-- • For each string which is not inside a function, translate it directly.
-- • Strings with keys named "format" are Lua regular expressions.
-- «()» is a match; «.+» means all characters; «%s+» means all spaces.
-- • For each string which is concatenated to the variable «var»,
-- translate the phrase assuming that «var» will be a noun.
-- • Remove any unnecessary translations.
