...to include another example, explain where CLASSOVERRIDE is set, add some notes, and link back to OVERRIDES:

  CLASSOVERRIDE:
    An internal variable specifying the special class override
    that should currently apply (e.g. "class-target", "class-native", and so
    forth). The classes that use this variable (e.g. [native.bbclass],
    [nativesdk.bbclass], and so forth) set it to appropriate values.
  
    Note {
    CLASSOVERRIDE gets its default "class-target" value from bitbake.conf.
    }
  
    As an example, the following override allows you to install extra files,
    but only when building for the target:
  
      do_install_append_class-target() {
          install my-extra-file ${D}${sysconfdir}
      }
  
    Here is an example where "python-native" is added to DEPENDS, but only when
    building for the build host:
  
      DEPENDS_append_class-native = " python-native"
  
    The underlying mechanism behind CLASSOVERRIDE is simply that is it included
    in the default value of [OVERRIDES].
