[gambit-list] getting up and running with swank-gambit

I tried downloading what seemed to be the latest version of swank-gambit at: https://github.com/shortsightedsid/swank-gambit Being a total lisp, scheme, and SLIME newbie, I'm having trouble getting off the ground with this. The swank-gambit README file reads: "Run swank-gambit.scm from the command line, and then type `M-x slime-connect ENT ENT ENT` to get a SLIME prompt." I tried running "gsi swank-gambit.scm" from a shell, but it just hangs, with no visible output. I suspect I'm grossly misunderstanding the instructions. Any help would be much appreciated. -- Matt
