Of MI.

Ok, guess I won't write texinfo for now, so plain text documentation
would be this:

	-list-features
		Returns a list of particular features of the MI protocol that
		this version of gdb implements.  A feature can be a command,
		or a new field in an output of some command, or even an
		important bugfix.  While a frontend can sometimes detect presence
		of a feature at runtime, it is easier to perform detection at debugger
		startup. The current list of features is:

		- 'frozen-varobjs' -- indicates presence of -var-set-frozen command,
		as well as possible presense of the 'frozen' field in the output of
		-varobj-create.
