Please note: 
1 - this module requires the CURL optional extension to connect to Amazon.com. Most wehosts provide it, but it's possible yours does not.
2 - When running under PHP4, this module requires the DOM XML optional extension. Again, it's possible your web host may not provide it, but most do.
3 - As of this writing (August 2005) ECS assumes all input is ISO-8850-1 encoded, even as it returns UTF-8. If you have the iconv module enabled, your search terms will be ISO-8850-1 encoded. This is important if you search in languages other than English.

The best way to find out if your host has these modules installed is to make a php file (say, phpinfo.php) containing this:

<?php
phpinfo();
?>

on your server and load it into your web browser (say, http://www.example.com/phpinfo.php).

TO UPGRADE FROM 4.6 to 4.7
-1: Back up your 4.6 files and the amazonnode and amazonitem tables
0: make sure you backed up your 4.6 files and the amazonnode and amazonitem tables
1: FTP the amazontools directory to your Drupal modules directory, overwriting the 4.6 versions of the files
2: When running upgrade.php, select the update 1 from the amazon module combo box  3: Optionally enable one or more book blocks on your site's admin/blocks page
There will be no need to execute the SQL statements in amazon.mysql. The version for 4.6 wasn't compatible with PostgreSQL so there is no upgrade.pgsql.


TO INSTALL FOR 4.7:

1: FTP the amazontools directory to your Drupal modules directory
2: Enable the module on your site's admin/modules page
3: Optionally enable one or more book blocks on your site's admin/blocks page
