title: How to clear the Cargo cache?
body: <p>When I run <code>cargo build</code>, various libs get stored within the folder <code>/usr/local/lib/rustlib/</code>.</p>
  
  <p>What is the correct way to clear these libs? I could <code>rm</code> these files manually, but would that be the right thing to do? I noticed that <code>/usr/local/lib/rustlib/manifest</code> is a file containing a list of the fill file paths of all the libs, and hence might be breaking something if I remove these files manually.</p>
