  ## The logo xonsh prints during build contains unicode characters, and this
  ## fails because locales have not been set up in the build environment.
  ## We can fix this on Linux by setting:
  ##    export LOCALE_ARCHIVE=${pkgs.glibcLocales}/lib/locale/locale-archive
  ## but this would not be a cross platform solution, so it's simpler to just
  ## patch the setup.py script to not print the logo during build.
