This defines alternative icons for IzPack GUI components, such as installer buttons and decorations.

sysicon

This defines alternative icons for Java Swing components, such as the buttons and decorations on built-in dialog boxes.

Here is an example of a customicons.xml file :

<izpack:icons version="5.0"
              xmlns:izpack="http://izpack.org/schema/icons"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://izpack.org/schema/icons http://izpack.org/schema/5.0/izpack-icons-5.0.xsd">
    <icon res="/resources/JFrameIcon" id="JFrameIcon"/>
    <icon res="/resources/next" id="stepforward"/>
    <icon res="/resources/previous" id="stepback"/>
</izpack:icons>

Resources 

One way to provide the icon files themselves, is to include them as resources in the <resources> section of the install spec. In this case, the res attribute for the icon spec in customicons.xml must be specified as "/resources/resource-id". 

...

This section lists and displays all standard IzPack icons that are used by default, along with the icon ID (which is needed for defining custom icons), and a brief description of where it's used. Replace these using an <icon> tag in customicons.xml.
