Directory Contents:
   grass4.0.cpio.Z   GRASS source code in compressed cpio format
   grass4.0.split    Directory containing the above file split into 1M chunks
       (updated to be identical with GRASS 4.0 release tape 13 Sept 91)
   spearfish.cpio.Z  Sample data base (meters)
   spear.split       Directory containing the above file split into 1M chunks
   world.cpio.Z      Sample world data base (latitude-longitude)
   manual.ps         Directory containing the GRASS manual in PostScript format
   intro.ps          User introduction to GRASS 4.0
   overheads.ps      Overheads appendix to "intro.ps"
   install.roff.ms   Installation instructions (see below)
   program.roff.ms   "GRASS Programming Changes"
   programming.ps    Postscript format of "GRASS Programming Changes"
   vector.ms         "GRASS Vector Library Changes"

Documents
   Process all *.ms documents through tbl(1) and troff (or equivalent)
   using the -ms macro package (except for programming.ps).

   All *.ps documenta are postscript - read for your postscript printer

On-line manual
   The on-line manual is included in the grass4.0.cpio.Z file.  You can
   print it locally by processing it through nroff/troff.  See the
   $GISBASE/man/utilities/imagen file (you'll learn about $GISBASE during
   GRASS installation) for a start.  Edit this file to reflect your
   local roff processors and printers and then run "imagen" on the
   roff files; e.g. imagen ../man1/*
   Expect hundreds of pages.

Installation
   The installation instructions are for sites receiving GRASS beta on
   tape.  If you are clever enough to access these files, you should
   have no difficulty in mentally editing the instructions to unpack
   and install these compressed cpio files.

I don't no about S code providing GIS capabilities, but
the GIS package "GRASS," developed by the Army Corps of
Engineers, has an "S interface" module.  GRASS is ftp'able
and also available supported for particular architectures
from private sources for a moderate fee (by GIS standards).
Unfortunately, the documentation for the recently released 
GRASS 4.0 refers only to S, not 'new newS' or even new S. 
The syntax examples given are clearly "old S."

As S data file formats have changed and macros have 
superceded functions, this is not terribly useful for S 
users who have stayed up to date with new releases.

So let me append to Marshall Feldman's query:  Has
anyone developed a new (or new new) S interface for an
existing GIS package (esp. GRASS, ARC/INFO, or ERDAS)?
