AbleCommerce Shopping Cart Software

I am using the CommerceBuilder class library to create stores, users, warehouses, etc. One of the requirements we have is to be able to do all of this transactionaly. How could I make the code below transactional (for store, warehouse and user creation) using the CommerceBuilder API? thanks, Mike //...

I have downloaded the CommerceBuilder Class Library docs, but are there any tutorials on how to use it?
