   Start up scheme as 
   scheme -edwin
   Once you have the scheme prompt issue the command
   (edit)
   An emacs-like buffer will appear and you can use C-h to get help.
   If you are running scheme from gnu-emacs you can also take advantage
   of the texinfo files provided.

This is only true of release 7.1 .
The -edwin flag did not exist in 7.0 .

In order to start it up under 7.0, assuming that you already have a
band (edwin.com) use

scheme -compiler -band <pathname>/edwin.com

The -compiler option is used to tell scheme to allocate more memory
than the default.  If no band was specified, it would load a compiler
band as well.

Once this starts up,

(edit)

should work.

The band can be constructed from the binaries in the edwin directory
by doing

(begin
  (with-working-directory-pathname
    "<edwin directory pathname>"
    (lambda ()
      (load "make")))
  (disk-save "<lib directory pathname>/edwin.com"))

The binaries can be constructed from the .scm sources by doing

(with-working-directory-pathname
  "<edwin directory pathname>"
  (lambda ()
    (load "edwin.sf")
    (load "edwin.cbf")))

in a Scheme with the compiler loaded.

I hope this helps.
