	---help---
		Enabled embedlog so you can disable it... sounds about right.

		Enable this to replace all embedlog function calls with stub
		functions that always return OK. This will effectively strip
		final binary from all log strings making code considerably
		smaller.

		This may be useful in two cases (at least):

		1) You develop your app on bigger version of target MCU, on
		which you have a lot of memory. So on that version of the
		build you can afford to enable good diagnostic logs. But
		final image may be run on smaller version, on which logs
		would not fit. In that case you can strip binary in final
		production image. Thanks to that you will get logs in dev
		env, but still maintain small footprint on production build.

		2) You want to hide implementation details that could be
		leaked with debug logs from final image.

		It only makes sense to enable this on production type builds.
		Linker will optimize out embedlog and remove all unused
		functions, just as if embedlog was never built.

		Enabling this will render embedlog example useless - it
		will not print anything, but example will stil compile
		and final image will be about 15kB smaller. But YMMV
		depending how much strings you have in project.
