How this all fits together
--------------------------

Let's look at a hypothetical example for how this all first together. Imagine,
if you will, a point about halfway between 1.5 and 1.6. At this point,
development will be happening in a bunch of places:

* On master, development towards 1.6 proceeds with small additions, bugs
  fixes, etc. being checked in daily.

* On the branch ``stable/1.5.x``, fixes for critical bugs found in
  the 1.5 release are checked in as needed. At some point, this branch will
  be released as "1.5.1", "1.5.2", etc.

* On the branch ``stable/1.4.x``, security fixes are made if
  needed and released as "1.4.2", "1.4.3", etc.

* Development of major features is done in branches in forks of the main
  repository. These branches will be merged into ``master`` before "1.6
  alpha 1".
