<note>
If you set <filename>PREFERRED_PROVIDER</filename>
for a <filename>virtual/*</filename> item, then any
recipe that
<link linkend='var-PROVIDES'><filename>PROVIDES</filename></link>
that item that is not selected by
<filename>PREFERRED_PROVIDER</filename> is prevented
from building, which is usually desirable since this
mechanism is designed to select between mutually
exclusive alternative providers.
