    A common binary file format representation on Mac OSX.

    On OSX, this is used to store user preferences, settings and application histories.

    It is also used to provide additional attributes for applications (such as type of

    document, icons etc.)

    Notice, that OSX is moving towards a new plist format, which is XML based.

    This decoder reads the old binary format. New applications should use the new format,

    and only use this decoder to convert/read old plist files.
