+/** @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>

+/** 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. */
