[BioPython] CVS and Fink Installations

Great!

Download the code from CVS, do "python setup.py build" as usual, but don't do
"python setup.py install". Then, when you want to use the CVS version, set
PYTHONPATH to the directory in which Biopython was built. For example, in my
case, that would be

export PYTHONPATH=/users/mdehoon/biopython/build/lib.linux-i686-2.5/

Then, if you do
>>> from Bio import something
it will import it from your code built from CVS.

You can do the same trick from inside Python; see the function main in
Tests/run_tests.py for an example.
