Added:

people/jd/scripts/check-conflicts.pl
Log:
Add the check-conflicts script. This checks for conflicting files in
packages which are currently in stable, testing and unstable. Run it
from the source directory below the debian dir.
Bugs and features:
* You may need to edit if to change which Contents.gz file it uses.
* Does not check non-US Contents.gz
* Should print out additional conflicts in debian/control
* Speed. apt-file takes ~3s to iterate Contents.gz. This takes ~36s to
iterate the file 3 times.
