You need to create `$GIT_DIR/rr-cache` directory to enable this
command.

+COMMANDS
+--------
+
+Normally, git-rerere is run without arguments or user-intervention.
+However, it has several commands that allow it to interact with
+its working state.
+
+'clear'::
+
+This resets the metadata used by rerere if a merge resolution is to be
+is aborted. Calling gitlink:git-am[1] --skip or gitlink:git-rebase[1]
+[--skip|--abort] will automatcally invoke this command.
+
+'diff'::
+
+This displays diffs for the current state of the resolution. It is
+useful for tracking what has changed while the user is resolving
+conflicts. Additional arguments are passed directly to the system
+diff(1) command installed in PATH.
+
+'status'::
+
+Like diff, but this only prints the filenames that will be tracked
+for resolutions.
+
+'gc'::
+
+This command is used to prune records of conflicted merge that
+occurred long time ago.
