-`blurb split` only needs to be run once per-branch, ever.
-It reads in `Misc/NEWS`
-and splits it into individual `.rst` files.
-The text files are stored as follows::
-
-    Misc/NEWS.d/<version>.rst

-`<version>` is the version number of Python where the
-change was committed.  Pre-release versions are denoted
-with an abbreviation: `a` for alphas, `b` for betas,
-and `rc` for release candidates.
-
-The individual `<version>.rst` files actually (usually)
-contain multiple entries.  Each entry is delimited by a
-single line containing `..` by itself.
-
-The assumption is, at the point we convert over to *blurb*,
-we'll run `blurb split` on each active branch,
-remove `Misc/NEWS` from the repo entirely,
-never run `blurb split` ever again,
-and ride off into the sunset, confident that the world is now
-a better place.
