Peering into Package Files

There are two ways to get more information from the Packages files, both through AptPkg::Cache::VerFile objects.

The FileList attribute of the AptPkg::Cache::Version object gives the list of package files (note: including the status file) which contain that version of the package:

      $cache->{$pack}{CurrentVer}{FileList}[0]
      $cache->{$pack}{VersionList}[0]{FileList}[0]

    are two examples of AptPkg::Cache::VerFile objects.

These objects may be used to fetch the information directly from the Packages file by seeking to Offset and reading Size bytes from the file given by File (attribute FileName).

Alternately, a subset of the record may be retrieved via the lookup method of the object returned by cache object's packages method.
