+       Usually 'git-gc' runs very quickly while providing good disk
+       space utilization and performance.  This option will cause

+       of taking much more time.  The effects of this optimization are

+The optional configuration variable 'gc.packrefs' determines if
+`git gc` runs `git-pack-refs`.  Without the configuration, `git-pack-refs`
+is not run in bare repositories by default, to allow older dumb-transport
+clients fetch from the repository,  but this will change in the future.

+The optional configuration variable 'gc.aggressiveWindow' controls how
+much time is spent optimizing the delta compression of the objects in
+the repository when the --aggressive option is specified.  The larger
+the value, the more time is spent optimizing the delta compression.  See
+the documentation for the --window' option in gitlink:git-repack[1] for
+more details.  This defaults to 10.
