I hadn't intended to start such a discussion here, although I'm glad
to get the comments.
The Athena Requirements Team did not ask us to support multiple
lockers with a single add command. While this does not necessarily
mean that we can't do it, it does complicate the implementation
considerably and I would want to go back to ART with this question.
Allowing the "-v" before the lockername is a good idea, I'm not sure
why I didn't think of it.
The authentication problem is easily addressed by using "-h -n" on the
optional invocation of attach. There's no other way to do this since
you can't get attach to tell you both the mount point and the
verbosity in one invocation.
No, add in .environment should not modify athena_manpath. MANPATH is
already set. Actually, it should modify both in case the user's
.environment resets MANPATH based on athena_manpath.
Revised diff:
