MULTIPLE PROCESS SUPPORT
===========================================================================
To run multiple Tcl processes, you start the first up with
M-x inferior-tcl. It will be in a buffer named `*inferior-tcl*'.
Rename this buffer with M-x rename-buffer. You may now start up a new
process with another M-x inferior-tcl. It will be in a new buffer,
named `*inferior-tcl*'. You can switch between the different process
buffers with C-x b.

Commands that send text from source buffers to Tcl processes -- like
`tcl-eval-defun' or `tcl-load-file' -- have to choose a process to
send to, when you have more than one Tcl process around. This is
determined by the global variable `inferior-tcl-buffer'. Suppose you
have three inferior Lisps running:
Buffer Process
foo inferior-tcl
bar inferior-tcl<2>
*inferior-tcl* inferior-tcl<3>
If you do a M-x tcl-eval-defun command on some Lisp source code, what
process do you send it to?

- If you're in a process buffer (foo, bar, or *inferior-tcl*),
you send it to that process.
- If you're in some other buffer (e.g., a source file), you
send it to the process attached to buffer `inferior-tcl-buffer'.
This process selection is performed by function `inferior-tcl-proc'.

Whenever M-x inferior-tcl fires up a new process, it resets
`inferior-tcl-buffer' to be the new process's buffer. If you only run
one process, this does the right thing. If you run multiple
processes, you might need to set `inferior-tcl-buffer' to
whichever process buffer you want to use.
