I'm running Squeak 3.0 on Linux.  I'd like to take a look at the Jitter
code for PPC and see how difficult it might be to port over to x86.

Can anybody help me get started by letting me know what sources I
should look at?  Are there any design documents?  Is most of the stuff
implemented in C or in Smalltalk?  Do people who run Squeak PPC routinely
use the Jitter, or do most people run the byte code interpreter regardless
of platform?

The latest version seems to be in a subdirectory called "j3" at
"ftp://www-sor.inria.fr/~piumarta/squeak/unix/", but it is not publically
accessible and hasn't been touched in 6 months.  Is there any other
place I should look?  Maybe on Sourceforge?

Thanks,
Thomas.
