This module has been modified by Ezra at Charles River Web (ezra@charlesriverweb.com) so that the quickbooks export has a list of line items for purchases, including shipping and donation fields.  It was based on the patch provided by Eileen Mcnaughton at http://drupal.org/node/498858.  That patch had to be modified as it was written for the development verison of uc_authorizenet.module.

A patch for 6.x-2.4 is included in this directory and submitted to the above drupal.org thread..  Upon upgrading ubercart, that patch may need to be modified and reapplied, provided that the new version of ubercart does not include the fix.  If that is the case, it may make sense to start with Ms. McNaughton's version, as it was written for the current development release.
