=head1 NAME
Dpkg::Control - parse and manipulate official control-like information
=head1 DESCRIPTION
The Dpkg::Control object is a smart version of L<Dpkg::Control::Hash>.
It associates a type to the control information. That type can be
used to know what fields are allowed and in what order they must be
output.
The types are constants that are exported by default. Here's the full
list:
=over 4
=item CTRL_UNKNOWN
This type is the default type, it indicates that the type of control
information is not yet known.
=item CTRL_TMPL_SRC
Corresponds to the first source package stanza in a F<debian/control> file in
a Debian source package.
=item CTRL_TMPL_PKG
Corresponds to subsequent binary package stanza in a F<debian/control> file
in a Debian source package.
=item CTRL_REPO_RELEASE
Corresponds to a F<Release> file in a repository.
=item CTRL_REPO_SRC
Corresponds to a stanza in a F<Sources> file of a source package
repository.
=item CTRL_REPO_PKG
Corresponds to a stanza in a F<Packages> file of a binary package
repository.
=item CTRL_DSC
Corresponds to a .dsc file of a Debian source package.
=item CTRL_DEB
Corresponds to the F<control> file generated by dpkg-gencontrol
(F<DEBIAN/control>) and to the same file inside .deb packages.
=item CTRL_FILE_BUILDINFO
Corresponds to a .buildinfo file.
=item CTRL_FILE_CHANGES
Corresponds to a .changes file.
=item CTRL_FILE_VENDOR
Corresponds to a vendor file in $Dpkg::CONFDIR/origins/.
=item CTRL_FILE_STATUS
Corresponds to a stanza in dpkg's F<status> file ($Dpkg::ADMINDIR/status).
=item CTRL_CHANGELOG
Corresponds to the output of dpkg-parsechangelog.
=item CTRL_COPYRIGHT_HEADER
Corresponds to the header stanza in a F<debian/copyright> file in
machine readable format.
=item CTRL_COPYRIGHT_FILES
Corresponds to a files stanza in a F<debian/copyright> file in
machine readable format.
=item CTRL_COPYRIGHT_LICENSE
Corresponds to a license stanza in a F<debian/copyright> file in
machine readable format.
=item CTRL_TESTS
Corresponds to a source package tests control file in F<debian/tests/control>.
=item CTRL_INFO_SRC
Alias for B<CTRL_TMPL_SRC>.
=item CTRL_INFO_PKG
Alias for B<CTRL_TMPL_PKG>.
=item CTRL_PKG_SRC
Alias for B<CTRL_DSC>.
=item CTRL_PKG_DEB
Alias for B<CTRL_DEB>.
=item CTRL_INDEX_SRC
Alias for B<CTRL_REPO_SRC>.
=item CTRL_INDEX_PKG
Alias for B<CTRL_REPO_PKG>.

=head1 METHODS
All the methods of L<Dpkg::Control::Hash> are available. Those listed below
are either new or overridden with a different behavior.
=over 4
=item $c = Dpkg::Control->new(%opts)
If the "type" option is given, it's used to setup default values
for other options. See set_options() for more details.
=cut
sub new {
my ($this, %opts) = @_;
my $class = ref($this) || $this;
my $self = Dpkg::Control::Hash->new();
bless $self, $class;
$self->set_options(%opts);
return $self;
}
=item $c->set_options(%opts)
Changes the value of one or more options. If the "type" option is changed,
it is used first to define default values for others options. The option
"allow_pgp" is set to 1 for CTRL_DSC, CTRL_FILE_CHANGES and
CTRL_REPO_RELEASE and to 0 otherwise. The option "drop_empty" is set to 0
for CTRL_TMPL_SRC and CTRL_TMPL_PKG and to 1 otherwise. The option "name"
is set to a textual description of the type of control information.
The output order is also set to match the ordered list returned by
Dpkg::Control::Fields::field_ordered_list($type).
