-/** @file
- * All actions handling saving and loading of the settings/configuration goes on in this file.
- * The file consists of four parts:
- * <ol>
- * <li>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.
- * <li>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.
- * <li>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.
- * <li>Handle saving/loading of the PATS chunk inside the savegame.
- * </ol>
- * @see SettingDesc
- * @see SaveLoad

-/** Settings-macro usage:
- * The list might look daunting at first, but is in general easy to understand.
- * We have two types of list:
- * 1. SDTG_something
- * 2. SDT_something
- * The 'G' stands for global, so this is the one you will use for a
- * SettingDescGlobVarList section meaning global variables. The other uses a
- * Base/Offset and runtime variable selection mechanism, known from the saveload * convention (it also has global so it should not be hard).
- * Of each type there are again two versions, the normal one and one prefixed
- * with 'COND'.
- * COND means that the setting is only valid in certain savegame versions
- * (since patches are saved to the savegame, this bookkeeping is necessary.
- * Now there are a lot of types. Easy ones are:
- * - VAR:  any number type, 'type' field specifies what number. eg int8 or uint32
- * - BOOL: a boolean number type
- * - STR:  a string or character. 'type' field specifies what string. Normal, string, or quoted
- * A bit more difficult to use are MMANY (meaning ManyOfMany) and OMANY (OneOfMany)
- * These are actually normal numbers, only bitmasked. In MMANY several bits can
- * be set, in the other only one.
- * The most complex type is INTLIST. This is basically an array of numbers. If
- * the intlist is only valid in certain savegame versions because for example
- * it has grown in size its length cannot be automatically be calculated so
- * use SDT(G)_CONDLISTO() meaning Old.
- * If nothing fits you, you can use the GENERAL macros, but it exposes the
- * internal structure somewhat so it needs a little looking. There are _NULL()
- * macros as well, these fill up space so you can add more patches there (in
- * place) and you DON'T have to increase the savegame version. */
