- 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
- Cornell University
- 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:
-
- dstool_bugs@cam.cornell.edu
