From 86dd9696d3a1acb036d65909d93d73455b8aed3a Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 19 Feb 2008 14:54:17 +0200 Subject: Revert ubi-tools changes Restore ubi tools to their "original" state, which means to the state they were before I stareted cleaning them up. Instead, create a "new-utils" subdirectory and move my work there.
