-%Description
-BusyBox combines tiny versions of many common UNIX utilities into a single
-small executable. It provides minimalist replacements for most of the utilities
-you usually find in fileutils, shellutils, findutils, textutils, grep, gzip,
-tar, etc.  BusyBox provides a fairly complete POSIX environment for any small
-or emdedded system.  The utilities in BusyBox generally have fewer options then
-their full featured GNU cousins; however, the options that are provided behave
-very much like their GNU counterparts.

+%description
+Busybox is a single binary which includes versions of a large number
+of system commands, including a shell.  This package can be very
+useful for recovering from certain types of system failures,
+particularly those involving broken shared libraries.

+%description petitboot
+Busybox is a single binary which includes versions of a large number
+of system commands, including a shell.  The version contained in this
+package is a minimal configuration intended for use with the Petitboot
+bootloader used on PlayStation 3. The busybox package provides a binary
+better suited to normal use.
