/* $Id$ */ /** @file * All actions handling saving and loading of the settings/configuration goes on in this file. * The file consists of four parts: *
    *
  1. Parsing the configuration file (openttd.cfg). This is achieved with the ini_ functions which * handle various types, such as normal 'key = value' pairs, lists and value combinations of * lists, strings, integers, 'bit'-masks and element selections. *
  2. Defining the data structures that go into the configuration. These include for example * the _patches struct, but also network-settings, banlists, newgrf, etc. There are a lot * of helper macros available for the various types, and also saving/loading of these settings * in a savegame is handled inside these structures. *
  3. Handle reading and writing to the setting-structures from inside the game either from * the console for example or through the gui with CMD_ functions. *
  4. Handle saving/loading of the PATS chunk inside the savegame. *
