#
# This makefile is intended to get you started in the setup of
# OpenEmbedded to build the OpenZipit distro.  To use this, 
# create a subdir in your user $HOME dir and put this makefile
# in there.  Go into that new dir and type "make".
# 
# This will then pull in all the OE sources and Zipit sources
# from the internet.  I do hope you have a fast internet
# connection!  OpenEmbedded is not "tiny" by any means, the initial
# "pull" of this makefile is about 270Meg.  The final "pull" from
# the web of the associated source files is about 166Meg.
#
# Pay attention to the final message from this makefile.  It will
# be telling you about adding to the PATH variable of your
# .bash_profile and a new BBPATH variable that will be needed.
