Usually downloading RodosLite is not required as it is integrated into the releases of JRodos and RODOS.
However, if you want to check the sources or want to update only the RodosLite part of your installation, a RodosLite package is available at the FTP server of FZK. For installation and compilation read the Administrator guide located in the docs directory of the RodosLite installation.
<note warning>Merging the downloaded version into your installation of JRodos or RODOS can totally mess up your installation. You should know exactly what you do.
You will be responsible for the outcome.</note>
