Control the ALSA mixer or generate JACK MIDI or OSC messages from rotary encoders and switches connected to GPIOs.
Currently, there is no way to specify an ALSA mixer device other than the default. This is quite limiting in setups with multiple soundcards (think one Hifiberry for the important...

As discussed at https://github.com/brgl/libgpiod/issues/31#issue-384105605 , libgpiod cannot currently do it, and it's arguably out of scope for a generic GPIO library until there is a generic universal kernel interface for...
For slave-only clients, the gpiod dependency is not technically necessary.
We have nicely modular help texts - it should be possible to print out only the relevant sub-section after a command line error was caught by the parser.
I get errors with osc.tcp:// URLs, but oscdump gets the same ones, so it's not me :)
in API versions newer than the one on Raspbian stretch, gpiod_ctxless_event_loop_multiple() is already marked deprecated. Maybe it's better to implement our own threading and resource management and use the low-level...
This will require replacing strtok in parse_cmdline.c/tokenize()
