Welcome to the online documentation of eZ components.
In beta1 there are a few new packages: DatabaseSchema, File and SystemInformation.
New in the online documentation representation itself is the pathstring that should make navigation a bit easier.
The API reference for each component is available through the component links on the left side.
A complete list of all the elements available can be found on the elements overview page and a list of all classes you can find here.
eZ components can be installed using a tar.gz/zip bundle or through the PEAR installer. The article An introduction to eZ components explains both installation methods.
