Fill @version tag with subversion in Eclipse

Question

I would like to fill the comment tag @version with Subclipse or Subversion in Eclipse. CVS has done this automatically but Subversion isn't. This would be very helpful.

I tried to google "@version" but it seems impossible.

Example what CVS did:

<?php
 /* 
 * @author Spankmaster
 * @version $Id: file.php,v 1.47 2009-09-21 09:28:49 sp Exp $
 * @package mysoftware
 */

Example with SVN:

<?php
 /* 
 * @author Spankmaster
 * @version $Id: $ -> stays empty
 * @package mysoftware
 */

Please help.....

Answer 1

in svn it is $Revision$

/**
* Last changed: $LastChangedDate$
* @author $Author$
* @version $Revision$
*/

also you must add the keywords to the project (folders and files)

Property svn:keywords set to LastChangedDate Author Id Revision HeadURL

Answer 2

thx to Marco and Davide.

Just to sum it all up for Eclipse Users:

This will change all files, so you will have to do a checkin of the complete project again. So check-in all work before doing that.

I rightclick on the project, select "Team -> set Property"

Property name: Enter "svn:keywords"

Enter a text property: Enter "LastChangedDate Author Id Revision HeadURL"

Check the option "Set property recursively"

Click "OK"
