[OE-core] why would a BBFILES variable refer to a "classes" directory?

[Robert P. J. Day]

  possibly a stupid question, but i'm looking at a publicly available
OE layer and, in layer.conf, there is a setting for BBFILES that pulls
in a number of subdirectories and ends with:

        ... snip ...
        ${LAYERDIR}/recipes-*/*/*.bbappend \
	${LAYERDIR}/classes/*.bbclass"

  i am unfamiliar with BBFILES used to include references to a classes
directory, and that layer.conf file already includes the earlier line:

  BBPATH := "${LAYERDIR}:${BBPATH}"

  can someone explain what BBFILES has to do with defining additional
classes in a layer? thanks muchly.
