APSW is a Python wrapper for the SQLite embedded relational database engine. In
contrast to other wrappers such as pysqlite it focuses on being a minimal layer
over SQLite attempting just to translate the complete SQLite API into Python.
The documentation has a section on the differences between APSW and pysqlite.
APSW supports CPython 2.3 onwards and CPython 3.1 onwards.

Optionally Python 3 extension will be built if Python 3 is installed.
