Subject: krino: 0.0.3 — the plan as one block per file, wrapped, and -P
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Each file shows its steps, then the rule and the reason it matched, one
field per line; on a terminal every line wraps to its width with
continuation lines under their own column, and piped output is never
wrapped. Choosing per file shows the same block. -P / --no-pager prints
the plan without the pager. A duplicate's original is shown with ~.
