[Swarm-Support] How do I use scripts to run swarm?

[Vegard Hartmann]

Hi,
I saw a post on the mailing list by Paul Johnson where he briefly mentions 
that he uses scripting tools to re-start swarm models. As I am new to 
Linux I do not know much about scripts. However, it would be very useful 
for me to use a script to run my application as I am having some memory 
leak problems. I use Fedora Core 2 and java.  I read all my simulation 
parameters from a scm file, and there are two values in this that needs to 
be changed from one run to the other, these are in the two lines below 
from my scm file:
#:loadFile "load.generation.hdf5"
#:saveFile "save.generation.hdf5"

My question is therefore how, or if it is possible, to write a script that 
runs my model several times, and for each time modifies the two lines 
above in my scm file?
