-- 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".
-- Then, for each 2nd and following argument, if map loading succeeds,
-- .success(map, filename) is run, otherwise .failure(filename, errmsg) --
-- these must be functions in the loaded module.

-- TODO: aggregate batch mode
