/// * never: no log rotation
/// * <n>: the file is rotated when its size exceeds

/// * <n> K: the file is rotated when its size exceeds
/// <n> Kilobytes.
/// * <n> M: the file is rotated when its size exceeds
/// <n> Megabytes.

/// The path of the (primary) log file can be specified with
/// the "path" property. Optionally, the path of the secondary
/// log file can be specified with the "secondaryPath" property.
