Summary: Version of busybox configured for use with petitboot

%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.
