[bitbake-devel] confused by explanation of OVERRIDES in BB user manual

[Robert P. J. Day]

  section 3.3.1:

     OVERRIDES = "architecture:os:machine"
     TEST = "default"
     TEST_os = "osspecific"
     TEST_nooverride = "othercondvalue"   <----- ?????

'In this example, the OVERRIDES variable lists three overrides:
"architecture", "os", and "machine". The variable TEST by itself has a
default value of "default". You select the os-specific version of the
TEST variable by appending the "os" override to the variable
(i.e.TEST_os).'

  what is the meaning of that line above with "nooverride"? i don't
recall that in earlier versions of the manual, and it doesn't seem to
be explained underneath it.
