Use emacs. :-)

This is really about the extent of the documentation that
is available without going to the official Open Firmware
spec as well. I recommend a large Cabernet Franc if you
go that route. :-) It is a known deficiency and it is being
worked on, just not fast enough for some. Please feel free
to post proposals or questions to the linuxppc-dev list too!

Please use git to obtain a current repository from jdl.com:
http://www.jdl.com/git_repos
git clone git://www.jdl.com/software/dtc.git
There is a newer tar file (dtc-20070216.tgz) in www.jdl.com/software
if you are unable to git clone the repo directly.

Please update your flex and bison in particular. If you do
not have a glr parser, your version is, like, years old now.
HTH,
