 == LRF ==
+The webinterface to lemon uses php and access to the backend.
+It also needs to know what machines to expect and based on their properties, how to group them.
+This is (for now) done with a nlist called NODES_PROPS.
+A basic example is 
+{{{
+## manual list, is respected when autocompleting
+variable NODES_PROPS  = nlist(
+        escape("egon.iihe.ac.be"),nlist('type','MON','monitoring','yes'),
+);
+}}}
+The name of the template that sets this variable is controlled through
+{{{
+variable LEMON_NODES_PROPERTIES_TEMPLATE ?= 'pro_nodes_properties';
+}}}
+The default value (ie behaviour in case it's not defined) for the {{{'monioting'}}} is controlled through
+{{{
+variable LEMON_NODES_PROPERTIES_DEFAULT_MONITORING ?= 'yes';
+}}}
