From 9d424a82f34de89920dee8ca4a45d42eafe55724 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Mon, 11 Aug 2008 18:08:09 -0700 Subject: [PATCH] Add a basic command line implementation of rm Removing entries from the index and from the working directory is a very trivial operation now that we have DirCacheBuilder able to do an update of the index, automatically keeping the paths that were skipped over by the TreeWalk. Therefore we only need to match the paths the user wants to remove, and do nothing with them. Signed-off-by: Shawn O.
