In such cases I tend to suggest installing ufed. 'tis a UI for setting use
flags. Not only does it show you the description of every flag and whether
it's local (used by only one or a few programs). It also shows you if it is
enabled (+ sign), disabled (- sign) or not touched (empty) and whether that
setting comes from the profile (parens) or your own setup (brackets).
