1 Description: Add support for latest .deb format members
2 This adds support for control.tar, control.tar.xz, data.tar, data.tar.xz
3 and data.tar.lzma in the dpkg and dpkg-deb applet. It also removes support
4 for control.tar.bz2 which has never been supported.
5 .
6 This should make these applets conform to deb(5).
