+initramfs-tools
+===============
+
+This package is a work in progress towards the replacement of the initrd
+system with an initramfs system.
+
+The goals include using klibc for all earlyspace tools, an integrated udev
+and an integrated hotplug.
+
+See the TODO file for a current status.
+
+Jeff Bailey - 2005-04-24
