[Scilab-users] Increasing Scilab default Java heap memory to 512 MB?

[Antoine Monmayrant]

That's the very first thing we change after installing scilab on all the 
computers in our group, so I agree we need to change it.
Is there a way to make people aware of this settings and tell them that 
it's related to plotting?
Like displaying a tip saying that they can crank it up when they need to 
display/export large plots and that it will add up to the memory used by 
scilab?
