The eZ Publish Kernel

Kernel modifications or overrides :: A warning

At times one needs to use intimidate knowledge of eZ publish internals (kernel) to archive certain specific functionality. It is generally _not_ recommended to change the kernel or stock eZ publish core, because upgrades will be much harder. Patches mean merges often by hand, which can become time consuming and or tedious.

If you really want to do it, learn more about the design of eZ publish, kernel limitations and solutions. Custom solutions based on eZ publish may find that kernel modifications are required to provide extended features or functionality. eZ Publish 4.0 provides the ability to cleanly override files in the kernel within a separate extension.
