       These are functions used by debget and related scripts, but you can use them, too.  I will do everything
       possible to retain backwards compatibility for the interfaces documented here.

       Most of these functions will "die" if they're called in a context (scalar, list) which doesn't match what
       they expect.  This is so that I will be able to change them to return something different in the other
       context without breaking old code.

       binary_package_info package
           This function returns some information about a binary package.

           If the package isn't found nothing is returned.  If it is found, the return value is a data structure
           like this:

               $r->{$distribution}{$architecture} = $version;
               # $distribution => 'stable', 'experimental', etc.
               # $architecture => 'i386', 'powerpc', etc.

           If something goes seriously wrong binary_package_info will "die".

       source_package_info package
           This function returns some information about a source package.

           If the package isn't found nothing is returned.  If it is found, the return value is a data structure
           like this:

               $r->{$distribution} = [$version, @binary_package_list];
               # $distribution => 'stable', 'experimental', etc.
               # $version      => '123.4-5', etc.
               # @binary_package_list => qw(nethack-common nethack-x11), etc.

       cmp_debian_versions v1, v2
           This  is like "cmp" for Debian package version numbers.  It is prototyped to take 2 scalar arguments,
           so it can be used as-is as a "sort" comparison function.

       upstream_version debian-version
           This returns the upstream version extracted from the given debian-version

       pool_dir package
           This returns the pool directory (starting at the "pool/"  level)  in  which  files  for  package  are
           stored.  package can be either a binary or source package name.
