# NOTE on USE="gnutls dane", gnutls[dane] is masked in base, unmasked

# Exim supports it but we cannot express the dep USE=dane when
# USE=gnutls is in effect only in package.use.mask, the only option we
# have left is to a) ignore the dependency (but that results in bug
# #661164) or b) mask the usage of USE=dane with USE=gnutls. Both are
# incorrect, but b) is the only "correct" view from dep-pointofview.
# Bug #925108 showed that DANE is basically non-optional with OpenSSL,
# so we make -dane mandatory to use gnutls. Bleh.
# We cannot express a required use for berkdb/gdbm/tdb correctly because
# berkdb and gdbm are both enabled in base profile
