Please complete the following list with your items:

* General dicussion about the CDD idea
** Where should it go?
** What are the biggest obstacles?
** CDD debuggers needs
*** How to best do fg debuging of test cases
*** How to best do bg extraction of test cases
**** Is our approach of using the debugger in console mode the right one?
 Jocelyn: For now, there is GUI debugger, TTY debugger, and I guess CDD debugger, but you are not obliged to be in "console" mode
 one can imagine a HTTP debugger, or even a silent debugger
*** Console debugger crashes (Arno can you provide details please)
 Jocelyn: TTY debugger is not perfect (not enough time to work on it), what should be done is
 1) change the "menu like control" by a "shell like control"
 2) having the debugger controller in a separate thread, this way we could support "interrupt" and so on
 3) ... many improvement, and support all the debugger functionality
** Console Menu (again Arno)
*** Multiple debuggers at the same time (large long term issue)
 Jocelyn: That might be possible, but this won't be that easy for now, however, I have been changing progressively the design to be more flexible, and to allow that in the future. Maybe ISE could plan this for 6.3 with other major design changes.
** Build system needs
*** How to do it properly on Windows? (Stefan, please provide details here)
 Jocelyn: Those days, I am integrating+updating works from es-make team (Bernd and others) into the trunk, this way it should be much more easier to build the EiffelStudio tools. Still in progress.
** Guided tour through debugger
** Guided tour through build system
** Unable to debug ES with ES (only Stefan and Andreas). Maybe Jocelyn can have a quick look.
** Capture and Replay
*** Compare ES Capture and Replay and Sel. Capture and Replay
 Jocelyn: ES provides "Execution Recording and Replay", or should I say "Review"
*** What are strengths and weaknesses?
*** Can approaches be combined for mutal benefit?
*** Where to go from here?
