in terms of that.

-- Generic map iterator.
-- The first cmdline arg is a name of a lua file (may be sans .lua) which must
-- be a module and is `require'd into this script, e.g. "stats" or "stats.lua".
-- First, a key named .init is looked up in the loaded module and if it exists,
-- it is run like .init(arg) (thus allowing it to parse the command-line
-- arguments and then potentially remove the ones it used).
-- If .init returns non-nil, this script aborts.
-- Otherwise, for each 2nd and following argument, if map loading succeeds,
-- .success(map, filename) is run, otherwise
-- .failure(filename, errmsg) is run if that key exists, or a standard error
-- message is printed to stderr.
-- Finally, if there is a .finish field in the module, it is run with no args.
