The Play Framework template comments syntax

When you want to create Play Framework template comments, use the @* ... *@ syntax. Here's a one-line comment:

@* COMMENT *@

Here's a multiline comment:

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

(You can format that however you want.)

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.
