 Update a collection

 Here are some use cases this operation could be used for:
 
-* Create a new account on BGG and transfer your collection: export the collection from the old account first, then use **bggcli** to import it
-* Make a bulk update for all or some of your games: export the collection from your account first, modify details in the CSV file (using a text editor, OpenOffice, MS Excel, or whatever) and use ``bggcli`` to import the file
