BOINC provides tools for creating and operating projects:

boinc/tools/	add	Adds objects to the database.
boinc/tools/	make_project	Creates a project
boinc/tools/	update_versions	Adds all relevant core client and application executables to download directory and database

Projects can create their own tools using the Python API (see Python framework) or the C++ API (db/db.h)
