// You may include any language pack before sfcart.js in your HTML    ||

// a script src BEFORE the <SCRIPT SRC="sfcart.js">... line.          ||
//  For example: <SCRIPT SRC="language-en.js"></SCRIPT>                ||

// =====================                                               ||
// * MonetarySymbol: string, the symbol which represents dollars/euro, ||
//   in your locale.                                                   ||
// * DisplayNotice: true/false, controls whether the user is provided  ||
//   with a popup letting them know their product is added to the cart ||
// * DisplayShippingColumn: true/false, controls whether the managecart||
//   and checkout pages display shipping cost column.                  ||
// * DisplayShippingRow: true/false, controls whether the managecart   ||
//   and checkout pages display shipping cost total row.               ||
// * DisplayTaxRow: true/false, controls whether the managecart        ||
//   and checkout pages display tax cost total row.                    ||
// * TaxRate: number, your area's current tax rate, ie: if your tax    ||
//   rate was 7.5%, you would set TaxRate = 0.075                      ||
// * TaxByRegion: true/false, when set to true, the user is prompted   ||
//   with TaxablePrompt to determine if they should be charged tax.    ||
//   In the USA, this is useful to charge tax to those people who live ||
//   in a particular state, but no one else.                           ||
// * TaxPrompt: string, popup message if user has not selected either  ||
//   taxable or nontaxable when TaxByRegion is set to true.            ||
// * TaxablePrompt: string, the message the user is prompted with to   ||
//   select if they are taxable.  If TaxByRegion is set to false, this ||
//   has no effect. Example: 'Arizona Residents'                       ||
// * NonTaxablePrompt: string, same as above, but the choice for non-  ||
//   taxable people.  Example: 'Other States'                          ||
// * MinimumOrder: number, the minium dollar amount that must be       ||
//   purchased before a user is allowed to checkout.  Set to 0.00      ||
//   to disable.                                                       ||
// * MinimumOrderPrompt: string, Message to prompt users with when     ||
//   they have not met the minimum order amount.                       ||
//                                                                     ||
// Payment Processor Options:                                          ||
// ==========================                                          ||
// * PaymentProcessor: string, the two digit payment processor code    ||
//   for support payment processor gateways.  Setting this field to    ||
//   anything other than an empty string will override your OutputItem ||
//   settings -- so please be careful when receiving any form data.    ||
//   Support payment processor gateways are:                           ||
//    * Authorize.net (an)                                             ||
//    * Worldpay      (wp)                                             ||
//    * LinkPoint     (lp)
//                                                                     ||
// Options For Programmers:                                            ||
// ========================                                            ||
// * OutputItem<..>: string, the name of the pair value passed at      ||
//   checkouttime.  Change these only if you are connecting to a CGI   ||
//   script and need other field names, or are using a secure service  ||
//   that requires specific field names.                               ||
// * AppendItemNumToOutput: true/false, if set to true, the number of  ||
//   each ordered item will be appended to the output string.  For     ||
//   example if OutputItemId is 'ID_' and this is set to true, the     ||
//   output field name will be 'ID_1', 'ID_2' ... for each item.       ||
// * HiddenFieldsToCheckout: true/false, if set to true, hidden fields ||
//   for the cart items will be passed TO the checkout page, from the  ||
//   ManageCart page.  This is set to true for CGI/PHP/Script based    ||
//   checkout pages, but should be left false if you are using an      ||
//   HTML/Javascript Checkout Page. Hidden fields will ALWAYS be       ||
//   passed FROM the checkout page to the Checkout CGI/PHP/ASP/Script  ||
