Hm. Before posting, I checked this:
So I got the impression that because the source is there (I admit *not*
checking the python source distribution itself though) and a library is
in the python-lib, that python ships with sqlite.
So - I stand corrected. Given the way some linux distros treat python
wrt to e.g. distutils, I wonder if there is one out there that does
*not* have sqlite built-in.
