-- Not linked and never synced -- write it by hand where it is wanted. Only
-- init.lua is linked into ~/.config/hammerspoon, so a file beside it there is
-- the machine's own and in no repo. init.lua loads it last, inside a pcall: it
-- can override anything set there, and a mistake in it is reported without
-- taking the rest of the config down.
--
-- Reload with ctrl-shift-alt-h, as with any other change.
--
-- The helpers are in dotlib.lua, linked beside init.lua. This header is the
-- same one init.lua has, names included, so a binding can be moved between the
-- two files unchanged -- which is how a machine takes something out of the
-- shared config, or the shared config adopts something that started here.
-- Anything not in the module is still reachable as hs.*.

-- loads -- so there is a function for it, which also clears the live mapping.
