title: How can I comment in the file denoted by javax.persistence.sql-load-script-source
body: <p>I'm using <code>javax.persistence.sql-load-script-source</code> for my unit testing.
  Is there any standard way to put comments on the script?</p>
  
  <p>The file contains insert statements for my entities.</p>
  
  <pre class="lang-sql prettyprint-override"><code>INSERT INTO ... (...) VALUES (...) -- 1
  INSERT INTO ... (...) VALUES (...) -- 2
  </code></pre>
  
  <p>I want to comment the generated id value for myself.</p>
  
  <p>P.S. I'm using H2, Derby, and HSQLDB as in-memory databases and EclipseLink and Hibernate as JPA implementations.</p>
