       dpkg-scanpackages - create Packages index files

       dpkg-scanpackages [option...] binary-path [override-file [path-prefix]] > Packages

       dpkg-scanpackages sorts through a tree of Debian binary packages and creates a Packages file, used by apt(8), dselect(1),
       etc, to tell the user what packages are available for installation. These Packages files are the same as those found on
       Debian archive sites and CD-ROMs. You might use dpkg-scanpackages yourself if making a directory of local packages to
       install on a cluster of machines.

       Note: If you want to access the generated Packages file with apt(8) you will probably need to compress the file with xz(1)
       (generating a Packages.xz file), bzip2(1) (generating a Packages.bz2 file) or gzip(1) (generating a Packages.gz file).
       apt(8) ignores uncompressed Packages files except on local access (i.e.  file:// sources).

       binary-path is the name of the tree of the binary packages to process (for example, contrib/binary-i386).  It is best to
       make this relative to the root of the Debian archive, because every Filename field in the new Packages file will start with
       this string.

       override-file is the name of a file to read which contains information about how the package fits into the distribution (the
       file can be compressed since dpkg 1.15.5); see deb-override(5).

       path-prefix is an optional string to be prepended to the Filename fields.

       If more than one version of a package is found only the newest one is included in the output. If they have the same version
       and only differ in architecture only the first one found is used.

       -t, --type type
           Scan for *.type packages, instead of *.deb.

       -e, --extra-override file
           Scan file to find supplementary overrides (the file can be compressed since dpkg 1.15.5).  See deb-extra-override(5) for
           more information on its format.

       -a, --arch arch
           Use a pattern consisting of *_all.deb and *_arch.deb instead of scanning for all debs.

       -h, --hash hash-list
           Only generate file hashes for the comma-specified list specified (since dpkg 1.17.14).  The default is to generate all
           currently supported hashes.  Supported values: md5, sha1, sha256.

       -m, --multiversion
           Include all found packages in the output.

       -M, --medium id-string
           Add an X-Medium field containing the value id-string (since dpkg 1.15.5).  This field is required if you want to
           generate Packages.cd files for use by the media access method of dselect.

       -?, --help
           Show the usage message and exit.

           Show the version and exit.

           Sets the color mode (since dpkg 1.18.5).  The currently accepted values are: auto (default), always and never.

           If set, it will be used to decide whether to activate Native Language Support, also known as internationalization (or
           i18n) support (since dpkg 1.19.0).  The accepted values are: 0 and 1 (default).

       dpkg-scanpackages outputs the usual self-explanatory errors. It also warns about packages that are in the wrong
       subdirectory, are duplicated, have a Filename field in their control file, are missing from the override file, or have
       maintainer substitutions which do not take effect.
