# Transform RELEASE_NOTES, split into "leader", and "major changes",
# split into major categories, and prepend dates to paragraphs.
#
# Input format: the leader text is copied verbatim; each paragraph
# starts with [class, class] where a class specifies one or more
# categories that the change should be listed under. Adding class
# info is the only manual processing needed to go from a RELEASE_NOTES
# file to the transformed representation.
#
# Output format: each category is printed with a little header and
# each paragraph is tagged with [Incompat yyyymmdd] or with [Feature
# yyyymmdd].
