pkg_chk verifies installed packages against pkgsrc.
The most common usage is 'pkg_chk -u -q' to check all installed packages or
'pkg_chk -u' to update all out of date packages.
For more advanced usage, including defining a set of desired packages based
on hostname and type, see pkg_chk(8).

If neither -b nor -s is given, both are assumed with -b preferred.
