It's quite possible that this used to be the case a few years ago, and
now one needs to specify a keypair by name.

You then want to make use of the EC2_BACKUP_FLAGS_AWS environment
variable:

$ export EC2_BACKUP_FLAGS_AWS="--key-name mykeypairname"
$ ./ec2-backup .

Your program can then either pass the flags directly to any aws(1)
invocations or extract the right paramenters for any API calls you might
make from this variable.
