[ic] cant find documentation for creating second shopping cart

[interchange-users@icdevgroup.org (John Allman)]

Hi - quick question. I've searched all over the place in the docs and on 
google using as many variations on the theme of multiple carts and 
second baskets and the like that i can think ofbut i cant find the 
documentation on how to create and maintain multiple shopping carts. I 
feel completely inept here and i'm sure it's just a case of entering the 
wrong keywords, but could somebody post a link?

thanks

John
