[Help-smalltalk] Just a few questions

[Jepri]

Hi all,
   I've been programming gnu-smalltalk for about a week now and it is 
pretty nice, even if I have to write everything inStudlyCaps.

Just a few questions, the sort of thing you expect form any newbie, but 
I can't find the answers anywhere.

How do I get at the contents of the system Transcript, or how do I 
intercept them without rewriting printNl in 'Object'?
Is there a way to run code automatically at startup (code that is in the 
image, I know how to 'run' a file)?
I ran across 'Semaphore' - is gnu smalltalk multithreaded, and how 
serious is the threading (cooperative or pre-emptive)? 
How do I start a thread?
