15  * Some information about savefiles:
16  *
17  * A savefile can contain:
18  *
19  * - General information (toplevel attributes, [multiplayer])
20  * This is present in all savefiles
21  *
22  * - [statistics]
23  * This is present in all savefiles but it's not handled by playcampaign/play_controller/saved_game.
24  * It's handled by savegame.cpp
25  *
26  * - [snapshot]
27  * If a savegame was saved during a scenario this contains a snapshot of the game at the point when
28  * it was saved.
29  *
30  * - [carryover_sides_start]
31  * At start-of-scenario saves this contains data from the previous scenario that was preserved.
32  *
33  * - [carryover_sides]
34  * In savefile made during the game, this tag contains data from [carryover_sides_start] that was not
35  * used in the current scenario but should be saved for a next scenario
36  *
37  * - [replay_start]
38  * A snapshot made very early to replay the game from.
39  *
40  * - [replay]
41  * A record of game actions that was made between the creation of [replay_start] and [snapshot].
42  *
43  *
44  * The following types of savegames are known:
45  *
46  * - Start of scenario savefiles
47  * These files only contain general information, statistics, and [carryover_sides_start]. When these
48  * saves are loaded, the scenario data is loaded form the game config using the next_scenario attribute
49  * from [carryover_sides_start].
50  *
51  * - Expanded Start of scenario savefiles
52  * Similar to normal Start-of-scenario savefiles, but the also contain a [scenario] that contains the
53  * scenario data. This type is only used internally and usually doesn't get written to the disk.
54  *
55  * - In-game savefile
56  * These files contain general information, statistics, [snapshot], [replay], [replay_start], [snapshot],
57  * and [carryover_sides]. These files don't contain a [carryover_sides_start] because both starting points
58  * ([replay_start] and [snapshot]) were made after [carryover_sides_start] was merged into the scenario.
59  *
60  * - Replay savefiles
61  * Like a in-game save made during linger mode, but without the [snapshot].
