meson-python is a Python build backend built on top of the Meson build system. It enables use of Meson for the configuration and build steps of Python packages. Meson is an open source build system meant to be both extremely fast, and, even more importantly, as user friendly as possible. meson-python is best suited for building Python packages containing extension modules implemented in languages such as C, C++, Cython, Fortran, Pythran, or Rust.
