How to split Icecast config file in smaller chunks and include them as entities

Icecast config

Lets say you have a lots of predefined mountpoints. Move them to separate XML file mount-points.xml
At the beggining of icetcast.xml add

<!DOCTYPE icecast [
  <!ENTITY mounts SYSTEM "mount-points.xml">
]>

and then add reference to mounts somewhere within your configuration file

&mounts;
