While the thought of not having to deal with oldish Sun shells was
certainly compelling, tracetool.py seems to require Python 2.6 and
breaks with Python 2.5.1 on Mac OS X v10.5 (the last version to support
ppc). Any chance you can fix this?

What I'm seeing when the command line options are correct is this:

Error: invalid trace backend
Please choose a supported trace backend.

And when not, I see the following amidst the usage information:

[...]
  --enable-trace-backend=B Set trace backend
  File "/Users/andreas/QEMU/qemu/scripts/tracetool.py", line 73
    except getopt.GetoptError as err:
                               ^
SyntaxError: invalid syntax
                           Available backends:
[...]

I.e. `python scripts/tracetool.py --list-backends` breaks.
