Thanks! Why don't you check in your proposed changes on a branch?

add -d+2 to the command line

Are you building on one platform for a different target? I haven't worked
out how that should work, if at all.

One possibility is to just add features.

No, but I do plan to provide an empty "user-setup.jam" file which users (or
configure scripts) can customize for particular installations.

Boost Python has specialized testing needs that don't apply to most other
projects, so the Jamfile is neccessarily more complex. I guess if we could
identify the general-purpose Python debugging stuff and separate it from the
rest, it might be a good idea. I'm open to suggestions.

> (BTW, I'd change the name of allyourbase.jam)

Agreed. I'm supposed to check this stuff into the main trunk soon; I'll try
to clean up some of the organization when I do that.
