# NOFFCHECK (2)

# If policy hook wants to run dgit (or something else in the dgit

# ENOENT, use the installed version.

+#
+# Exit status of the mirror hook is advisory only. The mirror hook
+# runs too late to do anything useful about a problem, so the only
+# effect of a mirror hook exiting nonzero is a warning message to
+# stderr (which the pushing user should end up seeing).
+#
+# If the mirror hook does not exist, it is silently skipped.
