Rosetta folder missing from ISIS install page
has rsync installation paths for all missions avaialable, but the rosetta subfolder is not being mentioned.
As ISIS offers rosetta tools, I just tried it out by assuming it is in
rosetta which seems to be correct, so this line should be added to the instructions page:
rsync -azv --delete --partial isisdist.astrogeology.usgs.gov::isis3data/data/rosetta data/
