    # The ModifyImageAttribute operation modifies an attribute of an AMI.
    #
    # Currently the only attribute supported is launchPermission. By 
    # modifying this attribute it is possible to make an AMI public or 
    # to grant specific users launch permissions for the AMI. To make the 
    # AMI public add the group=all attribute item. To grant launch permissions 
    # for a specific user add a userId=<userid> attribute item.
