It is a very simple script it try to catch the Internet host by extension in order to match it against the countries in europe so we may change the currency shown on our page to match the new regional feature by ccbill. It will work in reverse so everything that is not as an extension
Code:
$eu_countries = array("at","be","cy","fi","fr","de","gr","ie","it","lu","mt","nl","pt","si","es","mc","sm","va");
will become dollar ;)
