 1. What is it?
__________ _________ ________ _______ ______ _____ ____ ___ __ _

  ASpringies is a simulator  which allows you to interactively  create
and edit a system of masses and springs.  The parameters of the masses
and springs (such as mass elasticity and spring K) as well as those of
the  surrounding  system (such  as  air viscosity and gravity) can  be
changed.  These systems can be loaded and saved into a file.

  I  guess  you  could  use ASpringies for real  work, but it's really
intended to be a time waster.

  ASpringies is the Amiga port of the program 'xspringies' by Douglas
DeCarlo.



 2. Requirements
__________ _________ ________ _______ ______ _____ ____ ___ __ _

Kickstart V37 (2.0) or above, of course

  If you want to use the screen mode requester, you must at least have
asl.library V38 of Workbench 2.1.


MUI (Magic User Interface, version 2.2 or above(1))

  ASpringies' user interface is built upon MUI; since it is no  longer
allowed to  distribute  parts  of MUI, you have to  get and install it
yourself.  Please read the file 'ReadMe.mui' that came with ASpringies
on how to obtain it.


A Floting Point Coprocessor (FPU), or standard 68040 and above

  The differential equation solver of ASpringies does LOADS of  number
crunching.  Without such  a beast, ASpringies won't be able to perform
animation  at a  reasonable  speed. You  may recompile  the  code  for
non-FPU systems, but don't expect much fun (2).

----------------

1 ASpringies only makes use of features that were present in the
first public release of MUI, but a recompilation under V2.2 now requires
the user to have version 2.2 installed, too.

2 On  my A4000/40,  ASpringies  spends about  80% of  its  cpu time in
numerics, 15% are used for graphics rendering. I'd really  love to see
it on a 68060...



 3. Installation
__________ _________ ________ _______ ______ _____ ____ ___ __ _

  Just drag  ASpringies' drawer icon  anywhere you like. Sorry for not
supplying an Installer script. :-)



 4. Caveats
__________ _________ ________ _______ ______ _____ ____ ___ __ _

  ASpringies'  way of double buffering the animation screen isn't 100%
system compliant.   It  works on  any Amiga with  the  OLD, ECS or AGA
chipset, but owners of additional graphics hardware should be careful.

  Set  your graphics board  to the most compatible intuition emulation
or switch it to bypass mode.



 5. Legal Stuff
__________ _________ ________ _______ ______ _____ ____ ___ __ _

  You may use ASpringies for a period of 3 (THREE) days, any usage  of
it after this period is STRICTLY FORBIDDEN, you are an outlaw and have
to FEEL GUILTY if you continue using ASpringies after this period.  To
register   ASpringies,  send  AT  LEAST   50  Bucks  to  blah  blablah
blahblabla...

  STOP! NO WAY! Just kidding! ASpringies is FREE SOFTWARE (see below).
I really put a lot  of  work  in  it,  this  is my contribution to the
Amiga's user community.
