[Seaside] Re: What do you think about Ruby on Rails ?

Yes, but from the limited time I spent looking into it, it not so easy 
to execute  a program from squeak though. I got as far as loading the 
OSProcessPlugin before talk of using VMMaker got me thoroughly confused. 
Is there a simple guide on how to execute a shell command from Squeak 
that does not require me to compile a VM?
