That would also leave the name profile-trail (alias trail-profile) to
mean a profile where grades would include both profiling and trailing,
which otherwise not be covered.

On the listed profiles:
- If your project requires trailing, you probably really don't care
about non-trailing grades, except for the one used to build the
compiler. So I don't think trail should include all base grades.
- If incrementally installing, and grades are selected that are
already installed, are they re-installed? If so, I would rather that
debug and profile do not include the base grades either, since these
profiles are ones that are likely to be added after initial
installation (*). Developers can write base,profile,debug if they want
base grades up front.

Cheers,
Mark.

even though you are still waiting for the other tools to be installed.
