# Whether to handle debug or not.
# Some gnome applications support various levels of debugging (yes, no, minimum,
# etc), but using --disable-debug also removes g_assert which makes debugging
# harder. This variable should be set to yes for such packages for the eclass
# to handle it properly. It will enable minimal debug with USE=-debug.
# Note that this is most commonly found in configure.ac as GNOME_DEBUG_CHECK.
