From 1aed2fe394f45fed7b97e268cfa11d25c3d8da27 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Tue, 6 Dec 2011 18:43:35 +0100 Subject: [PATCH] Add test-scrap-cache-tree A simple utility that invalidates all existing cache-tree data. We need this for tests. (We don't need a tool to rebuild the cache-tree data; git read-tree HEAD works for that.)
