Noir::CLI::HelpCommand
noir help [command]
noir help (no args) prints the top-level overview. This is also
what noir with no arguments and noir -h resolve to.
noir help scan (etc.) defers to the matching command's help.
Constants
KNOWN_HELP_TARGETS = Noir::CLI::Catalog::NAMES
Commands recognised by noir help <cmd>. The same verbs the router
dispatches — route_for below maps each to its help printer, and a
catalog entry with no branch there is a compile error rather than a
verb that quietly has no help page.
