Inside TYPO3

3.3.2. config_default.php

The localconf.php file and equivalents from extensions are included from the config_default.php file. This file will set the default values in the $TYPO3_CONF_VARS array. This is also the ultimate source for information about each configuration option available! So please take a look into the source code of that file if you want to browse the full array of options you can apply!

This is a snippet from that file:

  

 <?php
 

 /**

* TYPO3 default configuration

*

* TYPO3_CONF_VARS is a global array with configuration for the TYPO3 libraries

* THESE VARIABLES MAY BE OVERRIDDEN FROM WITHIN localconf.php

*

* 'IM' is short for 'ImageMagick', which is an external image manipulation package available from www.imagemagick.org. Version is ABSOLUTELY preferred to be 4.2.9, but may be 5+. See the install notes for TYPO3!!

* 'GD' is short for 'GDLib/FreeType', which are libraries that should be compiled into PHP4. GDLib <=1.3 supports GIF, while the latest version 1.8.x and 2.x supports only PNG. GDLib is available from www.boutell.com/gd/. Freetype has a link from there.
