[Pharo-dev] Arguments to --trace=?

Anybody know where to find what the acceptable arguments to --trace on the command line are, and what each means? So far, I've tried: --trace Lots of output --trace=0 No output --trace=1 Looks maybe the same as --trace with no argument --trace=2 No output --trace=3 A whaling big lot of very interesting output Slightly better descriptions of these would be nice. :-) Thanks, -Martin
