/*
 * meson — the build system.
 *
 * Pure-python; installed by a plain file copy (no setuptools dependency):
 * meson.py becomes /usr/bin/meson and mesonbuild/ lands in the store
 * python's site-packages.  At runtime meson shells out to pkg-config and
 * ninja, so both must be on PATH when meson is used.
