Peewee integration with APSW, "another python sqlite wrapper".
Project page: https://rogerbinns.github.io/apsw/
APSW is a really neat library that provides a thin wrapper on top of SQLite's
C interface.
Here are just a few reasons to use APSW, taken from the documentation:
* APSW gives all functionality of SQLite, including virtual tables, virtual
file system, blob i/o, backups and file control.
* Connections can be shared across threads without any additional locking.
* Transactions are managed explicitly by your code.
* APSW can handle nested transactions.
* Unicode is handled correctly.
* APSW is faster.
