 # Sample TOML configuration file for building Rust.
 #
 # To configure rustbuild, copy this file to the directory from which you will be
 # running the build, and name it config.toml.
 #
 # All options are commented out by default in this file, and they're commented
 # out with their default values. The build system by default looks for
 # `config.toml` in the current directory of a build for build configuration, but
 # a custom configuration file can also be specified with `--config` to the build
 # system.
