Debian::Control - manage Debian source package control files
=head1 SYNOPSIS
my $c = Debian::Control->new(); # construct a new
$c->read($file); # parse debian/control file
$c->write($file); # write to file
print $c->source->Source;
print $c->source->Build_Depends; # Debian::Dependencies object
$c->binary->{'libfoo-perl'}->Description(
"Foo Perl module\n" .
" Foo makes this and that"
);
=head1 DESCRIPTION
Debian::Control can be used for representation and manipulation of Debian
source package control files in an object-oriented way. It provides easy
reading and writing of the F<debian/control> file found in Debian source
packages.
=head1 FIELDS
=over
=item source
An instance of L<Debian::Control::Stanza::Source> class. Contains the source
stanza of the Debian source package control file.
=item binary
A hash reference with keys being binary
package names and values instances of L<Debian::Control::Stanza::Binary> class.
Contains the information of the binary package stanzas of Debian source package
control file.
=item binary_tie
A L<Tie::IxHash> object tied to the B<binary> hash.

=cut

our $VERSION = '0.77';

use Parse::DebControl;
use Debian::Control::Stanza::Source;
use Debian::Control::Stanza::Binary;
=head1 CONSTRUCTOR
=over
=item new
Constructs a new L<Debian::Control> instance.
The C<source> field is initialized with an empty instance of
L<Debian::Control::Stanza::Source> and C<binary> field is initialized with an
empty instance of L<Tie::IxHash>.

}
=head1 METHODS
=over
=item read I<file>
Parse L<debian/control> and populate C<source> and C<binary> accessors.
I<file> can be either a file name, an opened file handle or a string scalar
reference.
=cut

$_->{Package} => Debian::Control::Stanza::Binary->new($_) );
}
else {
die "Got control stanza with neither Source nor Package field\n";
}
}
}
=item write I<file>
Writes a debian/control-like file in I<file> with the contents defined in the
C<source> and C<binary> fields.
I<file> can be either a file name, an opened file handle or a string scalar
reference.
All dependency lists are sorted before writing.

my ( $self, $file ) = @_;

}
}
if ( ref($file) and ref($file) eq 'SCALAR' ) {

}

}
else {
my $fh;
open $fh, '>', $file or die "Unable to open '$file' for writing: $!";
print $fh join( "\n", $self->source, $self->binary_tie->Values );
}
}
=item is_arch_dep
Returns true if the package is architecture-dependent. This is determined by
the C<Architecture> field of the first binary package. If it equals to C<all>,
then the package is architecture-independent; otherwise it is
architecture-dependent.
Returns I<undef> if it is not possible to determine whether the package is
architecture-dependent or not. This is the case when there are no binary
package stanzas present or the first has no C<Archiitecture> field.
=cut
sub is_arch_dep {
my $self = shift;
my $bin = $self->binary_tie->Values(0);
return undef unless $bin;
my $arch = $bin->Architecture;
return undef unless defined($arch);
return ( $arch ne 'all' );
