With ruby-debug, I start debugging via the "debugger" method in my
code, possibly conditional, in the exact place I want it. Couldn't be
happier!

Yes, it rdebug was an unfortunate name. In the rewrite [1], I don't
make that mistake. However currently that debugger is called rbdbgr
which I have come to learn that that is a very very bad name for the
project. I need to change that eventually -- different mistakes!

With regards to the question to the differences between debug.rb and
ruby-debug, others have answered this very nicely. Thanks! And there
is Pascal's blog on this from a while ago [2].

Nevertheless I'll try to summarize differences and note the possible
confusion on the next update of "Debugging with ruby-debug" [3].
