	  Opkg is a lightweight package management system, based on ipkg. It is

	  written in C and resembles apt/dpkg in operation. It is intended for

	  use on embedded Linux devices.

	  Opkg is maintained, stable, robust and conservative in its memory

	  usage, despite its buggy ipkg ancestry. As best it can, opkg

	  maintains backwards compatibility with ipkg and conforms to a subset

	  of debian's policy manual regarding control files.
