Having tinkered with these things, read the NEWS entry and read the relevant section of the manual, I am still completely in the dark.

According to the NEWS entry, option -R builds an auxiliary logic image. I tried this with a couple of examples and no images were built. According to the manual, this option opens the ROOT entry. It does seem to do that, though I'm not sure why this facility is needed.

Surely it wouldn't be difficult to add a few lines of text, describing the sort of situation in which this option is useful.
