Thank you for your responses and suggestions. But I don't think I was clear enough about what I meant by 'produce a disassembly'... I am developing a ppc assembly debugger for which I have my own crude disassembler. I would like to make this disassembly output a bit less crude by including program labels that may still be present in the ELF. To do this, I will need to understand the ELF data structure rather than relying on someone else's program or library.

At some point I will very likely also want to create my own ELF loader for this debugger so a language neutral explanation of ELF data structures would be very helpful as I don't like my chances of figuring this out via binary editor...
