krino: release 0.0.1 — man pages, install, examples, cross and release, README, changelogv0.0.1

Also: undo removes the directories its run created; a hardlink is never a
duplicate of its own other name; a flag written before "undo" is honoured;
--version prints no leading v. Duplicate conditions with different scopes
not sharing an original is documented as a known limitation.
