Short: All programs will pack/unpack data

PowerData	Patches AmigaDOS, enabling all programs to read and write
		files packed with PowerPacker in way that is completely
		transparent to themselves and the system.  Programs will read
		powerpacked datafiles directly, and will also magically start
		compressing their own datafiles, as they create or update
		them.  This is version 38.115, an update to version 38.105 on
		disk 801.  Partially localized for use with Workbench 2.1.
		Workbench 2.04+ only.  Shareware, binary only.
