Thanks to people who inform me new ideas. Some of these ideas are part
of the current version. Many thanks to Detlef from Hamburg, who show me the
advantage of using the international networks.
Also thanks to Bruno and Jim who help me to realize an english version
of GalaSimu, Werner and Volker for checking fortran sourcecode.



##### THIS DISKETTE INCLUDES:
 -   README.TXT  This text
 - GALASIMU.EXE  Simulating interacting galaxies (main program)
 - GALASIMU.HEL  Helpfile, required to start GalaSimu
 - GALASIMU.KNF  Initial file
 - GALASIMU.ICO  Icon for windows
 - GALASIMU.PIF  Program information file for windows
 - GALASIMU.EIN  Interacting galaxies?, required to start GalaSimu
 - GALASIMU.FOR  FORTRAN Sourcecode
 -     DEMO.BAT  Demonstration of several simulations automatically
 -  INSTALL.BAT  Installation batchfile running under MS-DOS
 -        *.SIM  Parameter files of simulations
 -        *.PCX  Pictures generated with galasimu



##### INSTALLATION by using INSTALL.BAT:
INSTALL.BAT should be run under DOS.
Start INSTALL.BAT with the following parameters:

INSTALL <sourcedrive> <destinationdrive>

Example: "INSTALL A: C:"         Follow the instructions.
The parameters sourcedrive and destinationdrive are necessary, otherwise
you get a warning.




##### INSTALLATION by user:
GalaSimu can be started either from floppy or harddisk.
GALASIMU.EXE, GALASIMU.HLP, GALASIMU.INI, GALASIMU.PIF, GALASIMU.ICO and
all *.SIM files must be present in same directory.
Copying to harddisk:
Copy the files GALASIMU.EXE, GALASIMU.HLP, GALASIMU.INI,
GALASIMU.PIF, GALASIMU.ICO and all *.SIM files in wished directory.




##### START PROGRAM:
Change into directory where GALASIMU.EXE is and type GALASIMU.




##### GALASIMU UNDER WINDOWS:
To run GalaSimu under windows, you can use the delivered files
GALASIMU.ICO and GALASIMU.PIF.
First, carry out the installation under dos described above.
Then start windows and choose in program-manager File/New/Programgroup/OK.
Type in the description "GalaSimu". Klick OK. A new group window with the
name GalaSimu appears.
Now, choose in the programm-manager File/New/Program/OK.
Type in the desciption "GalaSimu 1.3E". The entry commandline is the
command with the whole path to execute the program. This is according
to the installation performed above e.g. "C:\GALASIMU\GALASIMU.EXE".
Choose another symbol. The following message, that there is no symbol
available, confirm with OK. 
In the following dialog window type in the filename
"C:\GALASIMU\GALASIMU.ICO" and choose OK. The GalaSimu icon appears.
Klick OK and again OK. The installation is ready. The programgroup
"GalaSimu" with the program "GalaSimu 1.3E" is installed.
GALASIMU.PIF should be present in the same path as GalaSimu. For leaving
GalaSimu, you can type - as usually under windows - Alt+F4.

GalaSimu is original a dos application, so it can not run in a window
under windows. It can only run in full screen mode! These settings are
contained in the file GALASIMU.PIF.




##### END:
Finally, i hope you discover impressing simulations. You obtain a fantastic
view when regarding a simulation in a darkened room with a better three-
dimensional impression by a continious revolving with some degrees. The
particles leave behind tails. Try it!




##### HARDWARE REQUIREMENTS:
Required Computer: 2/3/4/586 with or without math. coprozessor, 495 kB
free RAM.
