 Hello,

 I have developed various profiling and debugging tools in the past, but
 haven't done any work in that direction for GHC compiled Haskell programs.
 I thought a good start might be to write a document detailing how the call
 stack works in GHC, and also write a basic debugger stack trace tool.
 Here:

 [https://github.com/blitzcode/ghc-stack]

 I hope this is helpful to people trying to pin down crashes, and people
 interested in working on debugging / profiling tools. I'd also really
 appreciate if somebody with more GHC / RTS knowledge than me would have a
 look and see if I got things right.

 Cheers,
 Tim
