# boinc_project_path.py - defines the directories where config.xml and
# run_state.xml are kept.
#
# You can override these defaults with one of these options:
#    1) modify this file directly (if you have only one project on your server
#       or have separate copies for each)
#    2) create a new boinc_project_path.py and place it earlier in PYTHONPATH
#       than the default one
#    3) define environment variables
