Compile .po files into .mo files.
This plugin adds build_mo, clean_mo and install_mo subcommands for
setup.py as well as hooking those into standard commands.
By default, setuptools_gettext compiles and installs mo files when there is a
po directory present that contains .po files.
The .mo files are installed adjacent to your package as package data in a subdirectory called locale.
You can override these settings in pyproject.toml:
[build-system]
requires = ["setuptools", "setuptools-gettext"]
...
[tool.setuptools-gettext]
# directory in which the .po files can be found
source_dir = "po"
# directory in which the generated .mo files are placed when building
build_dir = "breezy/locale"
