/**
|
|
* This works very similar to the host application defined in
|
|
* `individual-host.cpp`, but instead of just loading a single plugin this will
|
|
* act as a daemon that can host multiple 'grouped' plugins. This works by
|
|
* allowing the `libyabridge-{vst2,vst3}.so` instance to connect this this
|
|
* process over a socket to ask this process to host a VST `.dll` file using a
|
|
* provided socket. After that initialization step both the regular individual
|
|
* plugin host and this group plugin host will function identically on both the
|
|
* plugin and the Wine VST host side.
