That sounds more sensible - I had been wondering about
how that could be automated but it was late last night.

code, we could add something like this to setup.py

__version__ = "Undefined"
for line in open('Bio/__init__.py'):
     if (line.startswith('__version__')):
         exec(line.strip())

setup(
    name='biopython',
    version=__version__,
    author='The Biopython Consortium',
    ...

I'm happy to deal with this if we are agreed that we
should add a __version__ to Bio/__init__.py
(variations on the naming are possible, but this seems
to be a de-facto standard in python libraries).
