ruck-0.2.0 is not a library.
ruck is a Rust wrapper around the ChucK command line. All it does is pass its
arguments onto ChucK. It depends on having ChucK installed and in your PATH. The
undocumented --caution-to-the-wind flag is always passed to allow interoperability
with Rust, as this allows using the Std.system() function which is used to run
system commands.
