Use caution if you are trying to use the completeWays option. It's not
a good mix with the "tee" command right now because it makes temporary
files which store the entire dataset. It will do this once for each
"tee", so it could quickly chew up your disk space. Brett is working
on some changes which  will make this type of operation more practical
and only require one data set copy.
