Great.  Thanks for testing it.

No, you can give more than one file on the mig command line.

This is quite a lot of work to do at all properly.  It's not what I would
suggest as the next improvement to make.  Doing this requires a lot of work
on mig or on something else to examine the types in .defs files.

These seem potentially more useful, though I'm not sure how useful those
options are as described.  At this point we should have people using
rpctrace to debug and learn about the system.  From that real experience
people will see what other features they would like.

One place to start is looking at strace (Linux), truss (Solaris), and
ktrace (BSD) for what options they have that are easy to add to rpctrace.
For example, printing timestamps for each message.
