Python interface of Tkrzw
=========================

[Tkrzw](https://dbmx.net/tkrzw/) is a C++ library implementing DBM with various
algorithms. It features high degrees of performance, concurrency, scalability and
durability.

We build the following wheels:

- musllinux_1_2_x86_64
- manylinux_2_27_x86_64
- TODO: macos
- TODO: windows
