This file maps each file available in the backports.org archive system to the package from which it originates. It includes packages from the DIST distribution for the ARCH architecture. You can use this list to determine which package contains a specific file, or whether or not a specific file is available. The list is updated weekly, each architecture on a different day. When a file is contained in more than one package, all packages are listed. When a directory is contained in more than one package, only the first is listed. The best way to search quickly for a file is with the Unix `grep' utility, as in `grep CONTENTS': $ grep nose Contents etc/nosendfile net/sendfile usr/X11R6/bin/noseguy x11/xscreensaver usr/X11R6/man/man1/noseguy.1x.gz x11/xscreensaver usr/doc/examples/ucbmpeg/mpeg_encode/nosearch.param graphics/ucbmpeg usr/lib/cfengine/bin/noseyparker admin/cfengine This list contains files in all packages, even though not all of the packages are installed on an actual system at once. If you want to find out which packages on an installed Debian system provide a particular file, you can use `dpkg --search ': $ dpkg --search /usr/bin/dselect dpkg: /usr/bin/dselect FILE LOCATION
