The doc for DCOracle2 instructs the user to use PYTHONPATH.  The doc for
mxODBC does not, but instructs the user to use sys.path
I used the sys.path for mxODBC and it did not work.  So I added it to
PYTHONPATH envar and it worked.
So of course I am confused :)

Ok!  what setting does it look at then when one adds some library into its
own subdirectory and when one uses the import lib command to use something
from that lib?  sys.path?  is it the sure way?  Or is it to follow the
instructions that comes with the package?  Maybe I ran into some bad luck
then?  Since DCOracle2 and mxODBC did not behave as expected.  Well, they
are working now, but it bothers me that I had to go into all this trouble to
make them work :)
