Quick reference for myself and anybody interested:
1. Choose where you want breakpoints, and insert them like
# code above
breakpoint("Cool#identifier")
# code below
2. browse through your app until you hit the break
3. run to you console and launch
# ./script/breakpointer
There you go, here it comes a nice ruby session, with a few boons. Try playing with:
local_variables
source_lines
caller
