#@1702 Major mode for interacting with an inferior Scheme process.

The following commands are available:
\{inferior-scheme-mode-map}

A Scheme process can be fired up with M-x run-scheme.

Customization: Entry to this mode runs the hooks on `comint-mode-hook' and
`inferior-scheme-mode-hook' (in that order).

You can send text to the inferior Scheme process from other buffers containing
Scheme source.
    `switch-to-scheme' switches the current buffer to the Scheme process buffer.
    `scheme-send-definition' sends the current definition to the Scheme process.
    `scheme-compile-definition' compiles the current definition.
    `scheme-send-region' sends the current region to the Scheme process.
    `scheme-compile-region' compiles the current region.

    `scheme-send-definition-and-go', `scheme-compile-definition-and-go',
        `scheme-send-region-and-go', and `scheme-compile-region-and-go'
        switch to the Scheme process buffer after sending their text.
For information on running multiple processes in multiple buffers, see
documentation for variable `scheme-buffer'.

Commands:
Return after the end of the process' output sends the text from the
    end of process to point.
Return before the end of the process' output copies the sexp ending at point
    to the end of the process' output, and sends it.
Delete converts tabs to spaces as it moves back.
Tab indents for Scheme; with argument, shifts rest
    of expression rigidly with the current line.
C-M-q does Tab on each line starting within following expression.
Paragraphs are separated only by blank lines.  Semicolons start comments.
If you accidentally suspend your process, use \[comint-continue-subjob]
to continue it.

#@2009 The current scheme process buffer.

MULTIPLE PROCESS SUPPORT
===========================================================================
Cmuscheme.el supports, in a fairly simple fashion, running multiple Scheme
processes.  To run multiple Scheme processes, you start the first up with
\[run-scheme].  It will be in a buffer named *scheme*.  Rename this buffer
with \[rename-buffer].  You may now start up a new process with another
\[run-scheme].  It will be in a new buffer, named *scheme*.  You can
switch between the different process buffers with \[switch-to-buffer].

Commands that send text from source buffers to Scheme processes --
like `scheme-send-definition' or `scheme-compile-region' -- have to choose a
process to send to, when you have more than one Scheme process around.  This
is determined by the global variable `scheme-buffer'.  Suppose you
have three inferior Schemes running:
    Buffer	Process
    foo		scheme
    bar		scheme<2>
    *scheme*    scheme<3>
If you do a \[scheme-send-definition-and-go] command on some Scheme source
code, what process do you send it to?

- If you're in a process buffer (foo, bar, or *scheme*),
  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 `scheme-buffer'.
This process selection is performed by function `scheme-proc'.

Whenever \[run-scheme] fires up a new process, it resets `scheme-buffer'
to be the new process's buffer.  If you only run one process, this will
do the right thing.  If you run multiple processes, you might need to
set `scheme-buffer' to whichever process buffer you want to use.

More sophisticated approaches are, of course, possible.  If you find yourself
needing to switch back and forth between multiple processes frequently,
you may wish to consider ilisp.el, a larger, more sophisticated package
for running inferior Lisp and Scheme processes.  The approach taken here is
for a minimal, simple implementation.  Feel free to extend it.
