REQUIRED PARAMETERS
-i, --image Path to the image file to bundle.
-u, --user User ID (12-digit) of the user who is bundling the image.
OPTIONAL PARAMETERS
-c, --cert Path to the user's PEM encoded certificate.
-k, --privatekey Path to the user's PEM encoded private key.
-p, --prefix The prefix for the bundle image files. (default: image name).
--kernel The kernel to be associated with the bundled image.
--ramdisk The ramdisk to be associated with the bundled image.
-B, --block-device-mapping Default block device mapping for the image (comma-separated list of key=value pairs).
-d, --destination Directory to store the bundled image in (default: "/tmp"). Recommended.
--ec2cert_path The path to the Cloud's X509 public key certificate.
-r, --arch Target architecture for the image ('x86_64' or 'i386' default: 'x86_64').
--batch Run in batch mode (compatibility only. has no effect).
