- Improve descriptions of reset events, with reference to
the setup.tcl code which issues them.

1- Reviewing the code to catch various *missing* functions,

2- Alphabetizing and organizing. This chapter is a real
grab-bag with no evident focus or structural principle.
3- Hole-filling and bugfixing with respect to messaging/logging.
Example, what principle could possibly justify the tcl command
output going into the server output/log instead of just the
telnet session?
