The HqnFlatOut procset contains the showflat procedure, which can be used to send a flat description to the output plugin.
It consumes a flat description in the form of a dictionary (see the FlatOut manual for full details of a flat description) and sends it to your output plugin.
For example:
FlatDictionary /HqnFlatOut /Procset findresource /showflat get exec
sends the FlatDictionary flat description to the RIP for processing by your output plugin.
