blurb is a tool designed to rid CPython core development of the scourge of Misc/NEWS conflicts. The core concept: split Misc/NEWS into many separate files that, when concatenated back together in sorted order, reconstitute the original Misc/NEWS file. After that, Misc/NEWS could be deleted from the CPython repo and thereafter rendered on demand (e.g. when building a release). When checking in a change to CPython, the checkin process will write out a new file that sorts into the correct place, using a filename unlikely to have a merge conflict.
