# busybox.mk
# David Rowe May 2008
#
# Package to install busybox utilities missing from the uImage.
# Bit messy but saves a reflash of uImage for one missing
# busybox utility.
#
# usage: make -f busybox.mk busybox-package
#
# NOTES:
# 1/ make help in the busybox directory was quite helpful
#    in working out how to automatically configure busybox.
# 2/ Use 'make menuconfig' to set any utilities you would
#    like, then copy the .config file to file/busybox.config
# 3/ The latest msh shell looks much improved, might be work
#    including this, e.g as /bin/msh.
