This looks very promising. If I may check a couple of things, please:
  - what is the license?
  - any papers or other docs specific to ContextS?
  - dependencies? squeak 3.9? AspectS? others?
  - in your opinion, is it stable enough to use to develop a commercial app?
  - any thoughts on challenges of developing/debugging using ContextS?

btw: I tried loading
  ContextS.08Jul2330.cs.gz
directly in a 3.9 image and got a few errors with a Pragma: in 
CsAnnotationsTest (I think pragmas expect symbols rather than classes). I 
was able to skip these.

Many thanks,

Sophie
