-- Map is stored in a directory, which can be removed to generate a new map.
-- There is a command-line option for it: --map-dir
-- For a RUN_IN_PLACE build, it is located in:
-		../map

+--- Serialize an object into a source code string. This string, when passed as
+-- an argument to deserialize(), returns an object structurally identical to
+-- the original one.  The following are currently supported:
+--   * Booleans, numbers, strings, and nil.
+--   * Functions; uses interpreter-dependent (and sometimes platform-dependent) bytecode!
+--   * Tables; they can cantain multiple references and can be recursive, but metatables aren't saved.
+-- This works in two phases:
+--   1. Recursively find and record multiple references and recursion.

+-- @param x Value to serialize (nil is allowed).
+-- @return load()able string containing the value.
