[oe] Getting Started -Makefile

Mon Nov 19 12:08:19 UTC 2007

I think that my getting started Makefile is ready for testing.

To setup a development BitBake\OpenEmbedded system:

##Do not run this from an existing bb/oe directory.  It will##
##overwrite parts of your local.conf.                       ##

make a new  test directory
change to the test directory
copy Makefile to directory

$make setup
$make build-package-vim

This eliminates many of problems the new users have setting up bb
and oe.  There is no need to know any thing about svn of monotone.

I am caching sources in HOME to reduce traffic while testing.
I am still working on the quem testing image setup so I did not 
include it.

Thanks
David Farning
