Need some documentation regarding implementation of hook_omniture_variables()

Hi all,

I am trying to configure the Omniture Integration module in a Drupal 7 site. According to what I could gather by now, unlike in Drupal 5 here instead of the .inc file we define the variables with the hook_omniture_variables(). I couldn't find any documentation for this other than the sample code given in the omniture_basic.module file included with the module. But even after referring the code, I am unable to set and pass the various required variables like sitename, pagename, etc to Omniture reporting.

Can anybody please guide me with any information they have regarding using Omniture integration module for Drupal 7?

Thanks in advance!
