[Typo3] Typoscript and Linebreaks

[Robert Markula]

What is the "newline" character in Typoscript?
I would like to change the notification E-Mail of ve_guestbook, which is 
configured by plugin.tx_veguestbook_pi1._LOCAL_LANG.default.

In the locallang.php file it looks like this (lots of linebreaks):

   'notification_mail_text' => 'There is a new entry in your guestbook:

   Name: ###FIRSTNAME### ###SURNAME###
   E-Mail: ###EMAIL###
   Place: ###PLACE###
   Website: ###HOMEPAGE###
   Message: ###ENTRY###

   Click here to see the guestbook: ###URL###',

How do I get the same in TS?

Regards,
Ro
