[9fans] Scheme 9 ported to Plan 9

["Nils M Holm" <nmh@t3x.org>]

Scheme 9 from Empty Space (pun intended and originally a reference
to the movie, not to the OS) is an interpreter for R4RS Scheme.

In 2008 Bakul Shah pointed out that an interpreter with that name
should run on the Plan 9 OS and helped me port it. Ever since the
Plan 9 port has been in varying stages of bit rot.

After all the years I finally came around to straighten out some
rough edges of the Plan 9 port:

- the DEL key gets you back to the prompt instead of exiting the
  interpreter

- there is a target for system-wide installation in the mkfile
  (but S9 also runs in its source directory without installation)

- the HELP function works properly

So, if you are looking for a Scheme interpreter for Plan 9, look
no further! :)  http://t3x.org/s9fes

Enjoy!
