Where can I find docs on the commandline options for dBpa Batch Converter, C:/Program%20Files/dBpoweramp/Help/dMC/FileSelector.htm ?

I want to feed a source directory path on the commandline. If I supply just the directory path, it appears in the UI under Network, showing no audio files.

The only docs for this EXE I find file:///C:/Program%20Files/dBpoweramp/Help/dMC/FileSelector.htm do not mention the commandline.
