The bucket market-contracts-k3m6as holds the suppliers' terms. Lawyers want every past copy kept.

1. Turn on versioning for the bucket and check it.

2. Upload ~/terms.txt to the key terms.txt.

3. The supplier changed a clause. Open the file and change 30 days to 45 days:

   sh

   runcopy

   nano ~/terms.txt

4. Upload it to the same key again, then list the versions of terms.txt.
