This is a daemon for receiving and processing logs from the Linux Kernel, as
emitted over a network by the kernel's netconsole module. It supports both the
old "legacy" text-only format, and the new extended format added in v4.4.
The core of the daemon does nothing but process messages and drop them: in order
to make the daemon useful, the user must supply one or more "output modules".
These modules are shared object files which expose a small ABI that is called by
netconsd with the content and metadata for netconsole messages it receives.
