Major mode for editing Scheme code.
Editing commands are similar to those of lisp-mode.

In addition, if an inferior Scheme process is running, some additional
commands will be defined, for evaluating expressions and controlling
the interpreter, and the state of the process will be displayed in the
modeline of all Scheme buffers.  The names of commands that interact
with the Scheme process start with \"xscheme-\".  For more information
see the documentation for xscheme-interaction-mode.

Commands:
Delete converts tabs to spaces as it moves back.
Blank lines separate paragraphs.  Semicolons start comments.
