Parse::Debian::Packages - parse the data from a debian Packages.gz
SYNOPSIS
use YAML;
use IO::File;
use Parse::Debian::Packages;
my $fh = IO::File->new("Packages");
my $parser = Parse::Debian::Packages->new( $fh );
while (my %package = $parser->next) {
print Dump \%package;
}
DESCRIPTION
This module parses the Packages files used by the debian package management tools.
It presents itself as an iterator. Each call of the ->next method will return the next package found in the file.
For laziness, we take a filehandle in to the constructor. Please open the file for us.
METHODS
new( $filehandle )
next
Iterate to the next package in the file, returns either a hash containing a package description, or false at end of file.
as_hash( $filehandle )
Return all the packages from a filehandle as a hash of hashes.

dpkg-scanpackages - create Packages index files
SYNOPSIS
dpkg-scanpackages [option...] binary-path [override-file [path-prefix]] > Packages
DESCRIPTION
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 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 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.
OPTIONS -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 multicd access method of dselect.
-?, --help
Show the usage message and exit.
--version
Show the version and exit.
DIAGNOSTICS
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.
