My initial opinion on this is no. I think you are one of (if not the ??)
only person using the intel compilers on a Mac. Not only that, but this is
almost certainly bound to change. I think it's well-placed on a blog or
instruction site (such as one of the multitude we have on ambermd.org), but
is probably not well-placed in the manual.
