This file contains:
1. A brief description of the dstool program for the investigation
of dynamical systems, together with warranty and copyright
information.
2. Instructions for obtaining a copy of the program distribution
file and documents.
3. Brief descriptions for printing a copy of the installation
manual and an overview of the steps required to install
dstool on a Sun workstation.
I. dstool Program Description, Warranty and Copyrights
------------------------------------------------------
There is a critical need for computational environments that provide effective
tools for exploring dynamical systems with minimal effort on the part of the
user. Research that relies upon the investigation of dynamical systems would
be greatly enhanced by a standard, uniform environment for the exploration of
these systems with computers.
The explosion of the graphical computational capabilities of relatively in-
expensive desktop computers in the past few years makes the development of such
an environment both feasible and timely. The program described here, called
dstool (pronounce d dee-ess-TOOL), describes an implementation of one such
environment for the Sun UNIX workstation. It is an efficient research tool
that integrates a friendly graphical user interface, data management
capabilities, a rich set of numerical algorithms together with the
flexibility to add more algorithms and communicate data with other programs.
dstool has been implemented for use with the X Window system from MIT
and is based upon the program kaos, written by S. Kim and J. Guckenheimer.
The dstool program is the property of:
Cornell University
Center of Applied Mathematics
Ithaca, NY 14853
and may be used, modified and distributed freely, subject to the following
restrictions:
Any product which incorporates source code from the dstool
program or utilities, in whole or in part, is distributed
with a copy of that source code, including this notice. You
must give the recipients all the rights that you have with
respect to the use of this software. Modifications of the
software must carry prominent notices stating who changed
the files and the date of any change.
dstool is distributed in the hope that it will be useful, but WITHOUT ANY
WARRANTY; without even the implied warranty of FITNESS FOR A PARTICULAR
PURPOSE. The software is provided as is without any obligation on the part
of Cornell faculty, staff or students to assist in its use, correction,
modification or enhancement.
II. Obtaining a Distribution Copy of Dstool and Documentation
-------------------------------------------------------------
There are three ways to get a distribution copy of the dstool program:
Ethernet: The dstool distribution may be obtained from an archive server
supported by the Center for Applied Mathematics at Cornell
University. The server network address is cam.cornell.edu
(internet address: 132.236.122.12). Access to the server is best
accomplished using the ARPANET standard File Transfer Protocol
(ftp), a utility which facilitates the transfer of files between
network sites.
Diskette: The dstool program and manuals can be packaged on a set of 3.5
inch diskettes which may be read on a Sun diskette drive. In-
structions for extracting the software from the diskettes using
standard Sun operating system commands are presented in the in-
stallation manual.
Tape: Source code and documentation are stored on a 1/4 inch distri-
bution tape using the UNIX tape archive (tar) utility. Write to
authors enclosing a blank tape to get a distribution copy of dstool.
Instructions for reading the distribution tape are given in the in-
stallation manual.
Inquiries regarding tape and diskette distribution copies may be addressed to:
Attn: Dstool Distribution
Center for Applied Mathematics

305 Sage Hall
Ithaca, New York 14853
The following is a brief outline of the steps required to obtain a copy of
the dstool program and installation manual from the network:
Step 1: Create a subdirectory on your workstation for the dstool program
to reside. This file can have any name, but you must have permis-
sions for reading and writing in this subdirectory. We shall call
the name of this subdirectory the <dstool_dir> directory in the
steps that follow.
Step 2: Move to the dstool home directory if you are not already in it,
by typing:
cd <dstool_dir>
Step 3: In order to connect to the archive server, type:
ftp cam.cornell.edu
or
ftp 132.236.122.12
Step 4: Follow the login process with the user name anonymous and the
password anonymous. ---------
---------
Step 5: Once you have gained access to the system, move to the directory
pub/dstool by typing:
cd pub/dstool
Step 6: Put the ftp program in 'binary' mode with the command:
binary
Step 7: To list the files in this directory, type ls. To get the dstool
source file, type:
get dstool_1.1.tar
Step 8: To obtain a complete copy of the installation manual, in
PostScript format, type:
get install.ps.Z
The file is in compressed format. Consult your system manager
concerning the steps required to print a PostScript document
from your workstation.
Latex source for a no figures version of the documentation is
in the subdirectory Manuals_tex.
Step 9: After the file transfer is complete, exit ftp by typing quit.
----
Step 10: Restore the file system hierarchy by typing:
tar xvf dstool_1.1.tar
Step 11: Before you can begin the installation of dstool you must:
1. Set the environment variable DSTOOL to be the <dstool_dir>
directory where the program source will reside.
2. Check to insure the OPENWINHOME and LD_LIBRARY_PATH
environment variables are set properly for your OpenWindows
installation. Make sure $OPENWINHOME/lib is included in the
link path ( $LD_LIBRARY_PATH ).
3. Start-up the OpenWindows window system, if you have not
already done so.
4. Move to the <dstool_dir>/bin directory.
5. Begin the dstool installation by executing the shellscript
install_dstool and answering the questions.
-------------------------------------------------------------------------
| Note: The installation will not succeed if the environment variables |
| DSTOOL, OPENWINHOME and LD_LIBRARY_PATH are not set correctly. |
| Consult the dstool installation guide for further details. |
-------------------------------------------------------------------------
After unpacking, a list of libraries and include files used by dstool will
be found in $DSTOOL/site_specific/DEPENDENCIES. If your xview, olgx, or
X11 files are in different places than the standard Open Windows
Distribution, this will be a useful file to check.
If you are updating from Version 1.0, we suggest you install Version 1.1
in a new directory (e.g. /usr/local/dstool_1.1). Users will need to
update their DSTOOL environment variable to point to this directory.
They should also be told of the updating procedure described in the
file $DSTOOL/USER_UPDATING.
If you would like to be included on a dstool mailing list to receive
notices about dstool updates, future releases, and bug fixes, please
send your e-mail address to:
dstool-list@cam.cornell.edu
Please address all other correspondence and bug reports to:
