Also, wouldn't it be cool if Jengaboot output a script called ./debug that bootstrapped the time traveling debugger? (Which does have decent value printing out of the box)?

I have another idea. We can introduce rebel.debug field in the config. We can print stuff like the what ocaml dep return and what are the targets and dependecies of certain action. It is a bit primitive but can work as as stop gap solution while we figure out stuff.

That seems like a totally different feature (still useful)
