Hi,

it is possible to remove both tart.sh and tart.cmd by adding setup.py and its entry_points directive, which is more cleaner solution and remove some problems with PYTHONPATH. It's somehow done in my fork ( https://bitbucket.org/yedpodtrzitko/blackberry-py/commits/038fd35952140d26fa0721628c24f13a1b09bba7 ).
