define Package/opkg/Default/description
  Lightweight package management system
  opkg is the opkg Package Management System, for handling
  installation and removal of packages on a system. It can
  recursively follow dependencies and download all packages
  necessary to install a particular package.

  opkg knows how to install both .ipk and .deb packages.
