The Play Framework template comments syntax

When you want to create Play Framework template comments, use the @* ... *@ syntax.

Single line Play Framework comment

Here's a one-line Play Framework comment:

@* COMMENT *@

Multi-line Play comment

Here's a multi-line Play comment:

@*
 * Four score
 * and seven year ago
 * our fathers ...
 *@

(You can indent that however you want.)

More Play Framework comments info

You can use comments as the first line of Play Framework templates (before the function declaration):

@*************************************
 * The 'Hello, world' page           *
 *                                   *
 * @param msg The message to display *
 *************************************@
@(msg: String)

<h1>Hello, world</h1>

I found this information on the Play Framework Templates Syntax page.
