OPTIONS
-------
+--stale-fix::
+ This revamps the logic -- the definition of "broken commit"
+ becomes: a commit that is not reachable from any of the refs and
+ there is a missing object among the commit, tree, or blob
+ objects reachable from it that is not reachable from any of the
+ refs.
++
+This computation involves traversing all the reachable objects, i.e. it
+has the same cost as 'git prune'. Fortunately, once this is run, we
+should not have to ever worry about missing objects, because the current
+prune and pack-objects know about reflogs and protect objects referred by
+them.
+
--expire=<time>::
Entries older than this time are pruned. Without the
option it is taken from configuration `gc.reflogExpire`,
--all::
Instead of listing <refs> explicitly, prune all refs.
+--verbose::
+ Print extra information on screen.
