47 This is a simple port of the old jackdmp.cpp file to use the new jack2 control API. Available options for the server
48 are "hard-coded" in the source. A much better approach would be to use the control API to:
49 - dynamically retrieve available server parameters and then prepare to parse them
50 - get available drivers and their possible parameters, then prepare to parse them.
