Another advantage of the override style operations is that
you can combine them with other overrides as described in the
to "Z", and then further appended with
"X" leaving the variable set to "ZX".
Finally, applying the override for "foo" results in the conditional
- variable <filename>A</filename> becoming "Z X" (i.e.
+ variable <filename>A</filename> becoming "ZX" (i.e.
<filename>A</filename> is replaced with <filename>A_foo</filename>).
