	@item @code{--enable-newglobals} (EXPERIMENTAL)
	Enables a new and modernized global handler. This global handler has a number of known bugs, and thus should be used with caution.

	Note that global files created in the default global handler are incompatible with the new global handler, and vice-versa. You will need to back up and remove all globals in your environments when switching global handlers.
