If the experts are in slight disagreement as above, let me explain what I want to do. First, I plan to read on Bazaar in some days and prepare a debian/ubuntu with bazaar to download the repository. I certainly want to isolate from this big collection of the subset directory structure of the earliest and simplest and minimal emacs. I am not interested at this stage in any latest emacs. I want some _qualified_ suggestions on which would be the most instructive release to play with. This exercise at this stage is for purely educational purpose - as we appreciate the value of pure maths, pure science and pure research. Contributions in this way comes later with strong inspiration. People's minds work differently. To facilitate refererral to various versions of emacs (in the absence of bazaar working as yet on my system) here is a chart I have. I am wondering what kind of gui chart will bazaar show to me.
