title: How do you comment in the sbt repositories file?
body: <p>I'm using proxy repositories with sbt. I have many repositories to list in the repositories file so I'd like to add comments. The sbt reference manual doesn't mention the proper way to do this - <a href="https://www.scala-sbt.org/1.0/docs/Proxy-Repositories.html" rel="noreferrer">https://www.scala-sbt.org/1.0/docs/Proxy-Repositories.html</a>. Does anyone know?</p>
