atos and DWARF

It looks like atos (Xcode 3.0 install) now supports the DWARF symbol
format. Is that correct? At least it seems to be giving me correct
line information in the simple tests I have done so far against a C++
library built with DWARF symbols.

However... it looks like atos doesn't understand how to get symbol
information out of a dSYM file... or at least I can't get it to work
for me just yet.

I see "If you're using DWARF dSYM files, you must be using the version
of atos included in Xcode 3 (Mac OS X version 10.5)" in some online
docs [1].

We use dsymutil in our "for release" build process to generate a dSYM
file from a fully symboled version of our application (using DWARF).
We save the dSYM file and unstripped version and ship a stripped
version to our customers.

When I attempt to use atos against my application it doesn't list line
number information and often lists no information about the symbol at
given addresses. If I use info line in gdb it works.

Still testing this out but I wanted to see if anyone could outline
what is expected.
