title: Where does `go get` store what it downloads?
body: <p>I have been informed to use <code>go get &lt;github-URL&gt;</code> to download a <code>go</code> program.</p>
  
  <p>The command exists with no output and exit code <code>0</code>.</p>
  
  <p>On my system both <code>$GOPATH</code> and <code>$GOROOT</code> are unset.</p>
  
  <p>Where did <code>go</code> store my downloaded program?</p>
