=head1 NAME

AptPkg::PkgRecords - APT package description class

=head1 SYNOPSIS

use AptPkg::PkgRecords;

=head1 DESCRIPTION

The AptPkg::PkgRecords module provides an interface to the parsed
contents of package files.

=head2 AptPkg::PkgRecords

The AptPkg::PkgRecords package Implements the B<APT> pkgRecords class.

An instance of the AptPkg::PkgRecords class may be fetched using the
C<packages> method from an AptPkg::Cache object.

=head3 Methods

=over 4

=item lookup(I<PACK>)

Return a hash (or hash reference, depending on context) for the given
package.

I<PACK> may either be an AptPkg::Cache::VerFile object, an
AptPkg::Cache::DescFile object or a package name.

The hash contains the following keys:

=over 4

C<FileName>, C<Checksum-FileSize>, C<MD5Hash>, C<SHA256>, C<SourcePkg>,
C<Maintainer>, C<ShortDesc>, C<LongDesc> and C<Name>.

=back

with values taken from the packages or translation file.

Note that C<LongDesc> is generally not useful for AptPkg::Cache::VerFile
objects, which refer to the Packages file, as these no longer contain the full
description (now in the Translation files).

If I<PACK> is a package name, these additional values are set:

=over 4

C<Section> and C<VerStr>.

=back

and the following values are overridden with the translated versions:

=over 4

C<ShortDesc> and C<LongDesc>.
