From d11b8d342529a8fe2164ceb563ad9213902d3533 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 20 May 2009 11:04:35 -0700 Subject: [PATCH] write-tree --ignore-cache-tree This allows you to discard the cache-tree information before writing the tree out of the index (i.e. it always recomputes the tree object names for all the subtrees). This is only useful as a debug option, so I did not bother documenting it.
