HOW TO INSTALL GOOGLE CHECKOUT MODULE FOR OSC (v1.4Alpha1)

If you haven't read the README file yet, please read it first.

UPDATE from v1.3
================

Since this new version is very different, its recommended to remove all v1.3*
and re install from scratch the new v1.4 (more info see UPGRADE file)  

IMPORTANT: Uninstall and re install the module. If not, many new configuration 
  will not be enabled.

--------------------------------------------------------------------------------

FRESH INSTALL
=============

There are two installation options you need to choose from, so please read
 carefully to determine which option is right for you.

OPTION A:
=========
If you have the basic osCommerce installation without any other modules or
 add-on's, simply copy the provided files into your osCommerce system,
 preserving the file structure. 

 For your reference, here is the list of files you need to copy over to your
 system:

* Note: If you applied a patch or manually modified the files to disable 
   register_globals, go for Option B.

OPTION B:
=========

If you have other modules installed on your osCommerce installation, replacing 
 your existing files might break your existing installation. In this case, you 
 need to edit the existing files manually.

 For this option, follow the instructions below:

 I. Copy the following new files into your existing system, preserving the file structure:
