From 16cc345d4f84367e70e133200f7aa335c2aae8c6 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 18 Jun 2012 22:30:26 +0930 Subject: TDB2: Goodbye TDB2, Hello NTDB. This renames everything from tdb2 to ntdb: importantly, we no longer use the tdb_ namespace, so you can link against both ntdb and tdb if you want to. This also enables building of standalone ntdb by the autobuild script.
