From 3d4e8889889e5e36302454225999f7e146d3219c Mon Sep 17 00:00:00 2001 From: nwhitehorn Date: Wed, 12 Jan 2011 14:55:02 +0000 Subject: Update dialog to version 20100428. This changes the license under which dialog is distributed from GPLv2 to LGPLv2 and introduces a number of new features and a new and better libdialog API. The existing libdialog will be kept temporarily as libodialog for compatibility purposes until sade, sysinstall and tzsetup have been either updated or replaced. __FreeBSD_version is now 900030.
