See the section on Python in the Software Prerequisites.

Structure

The directory boinc/py/Boinc contains the Boinc module. This means if you have boinc/py/ in your python path you can write for example:
from Boinc.setup_project import *
To ensure boinc/py/ is in your python path:
import boinc_path_config
This is a special kludge module that configure places in relevant directories which then modifies sys.path appropriately.

Project-specific settings

The module boinc_project_path is imported to get the paths for config.xml and run_state.xml. The default paths for these are the parent directory of the invocation script. You can override these defaults
  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
Example boinc_project_path.py 
  config_xml_filename = '/etc/boinc/yetiathome/config.xml'
  run_state_xml_filename = '/var/lib/boinc/yetiathome/run_state.xml'
See the source of file boinc/py/Boinc/boinc_project_path.py for details.

Python modules in boinc/py/Boinc/

boinc_path_config.py.in Configure puts boinc_path_config.py in all directories that need it; see above
boinc_project_path.py sets where config.xml et al can be found; see above.
configxml.py reads and writes config.xml and run_state.xml - see its pydoc for more information
boinc_db.py auto-generated file that contains database constant definitions, e.g. RESULT_OUTCOME_SUCCESS = 1
setup_project.py module fore creating a project. Use
database.py defines database backend functions and database operations.
db_mid.py "middle-end": optional mix-in to ease debugging by allowing printing of database objects directly
