43/// Config Settings Documentation.
44/// At the TOP LEVEL, e.g. in OpenSim.ini, we have the following options:
45/// EACH REGION, in OpenSim.ini, can have the following settings under the [AutoBackupModule] section.
46/// IMPORTANT: You may optionally specify the key name as follows for a per-region key: <Region Name>.<Key Name>
47/// Example: My region is named Foo.
48/// If I wanted to specify the "AutoBackupInterval" key just for this region, I would name my key "Foo.AutoBackupInterval", under the [AutoBackupModule] section of OpenSim.ini.
49/// Instead of specifying them on a per-region basis, you can also omit the region name to specify the default setting for all regions.
50/// Region-specific settings take precedence.
51///
52/// AutoBackupModuleEnabled: True/False. Default: False. If True, use the auto backup module. This setting does not support per-region basis.
53/// All other settings under [AutoBackupModule] are ignored if AutoBackupModuleEnabled is false, even per-region settings!
54/// AutoBackup: True/False. Default: False. If True, activate auto backup functionality.
55/// This is the only required option for enabling auto-backup; the other options have sane defaults.
56/// If False for a particular region, the auto-backup module becomes a no-op for the region, and all other AutoBackup* settings are ignored.
57/// If False globally (the default), only regions that specifically override this with "FooRegion.AutoBackup = true" will get AutoBackup functionality.
58/// AutoBackupInterval: Double, non-negative value. Default: 720 (12 hours).
59/// The number of minutes between each backup attempt.
60/// If a negative or zero value is given, it is equivalent to setting AutoBackup = False.
61/// AutoBackupBusyCheck: True/False. Default: True.
62/// If True, we will only take an auto-backup if a set of conditions are met.
63/// These conditions are heuristics to try and avoid taking a backup when the sim is busy.
64/// AutoBackupScript: String. Default: not specified (disabled).
65/// File path to an executable script or binary to run when an automatic backup is taken.
66/// The file should really be (Windows) an .exe or .bat, or (Linux/Mac) a shell script or binary.
67/// Trying to "run" directories, or things with weird file associations on Win32, might cause unexpected results!
68/// argv[1] of the executed file/script will be the file name of the generated OAR.
69/// If the process can't be spawned for some reason (file not found, no execute permission, etc), write a warning to the console.
70/// AutoBackupNaming: string. Default: Time.
71/// One of three strings (case insensitive):
72/// "Time": Current timestamp is appended to file name. An existing file will never be overwritten.
73/// "Sequential": A number is appended to the file name. So if RegionName_x.oar exists, we'll save to RegionName_{x+1}.oar next. An existing file will never be overwritten.
74/// "Overwrite": Always save to file named "${AutoBackupDir}/RegionName.oar", even if we have to overwrite an existing file.
75/// AutoBackupDir: String. Default: "." (the current directory).
76/// A directory (absolute or relative) where backups should be saved.
77/// AutoBackupDilationThreshold: float. Default: 0.5. Lower bound on time dilation required for BusyCheck heuristics to pass.
78/// If the time dilation is below this value, don't take a backup right now.
79/// AutoBackupAgentThreshold: int. Default: 10. Upper bound on # of agents in region required for BusyCheck heuristics to pass.
80/// If the number of agents is greater than this value, don't take a backup right now.
81///
