+
+Dpkg::Control - parse and manipulate official control-like information
+
+=head1 DESCRIPTION
+
+The Dpkg::Control object is a smart version of 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:

+=item CTRL_UNKNOWN
+
+This type is the default type, it indicates that the type of control
+information is not yet known.
+
+=item CTRL_INFO_SRC
+
+Corresponds to the first block of information in a F<debian/control> file in
+a Debian source package.
+
+=item CTRL_INFO_PKG
+
+Corresponds to subsequent blocks of information 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_INDEX_SRC
+
+Corresponds to an entry in a F<Sources> file of a source package
+repository.
+
+=item CTRL_INDEX_PKG
+
+Corresponds to an entry in a F<Packages> file of a binary package
+repository.
+
+=item CTRL_PKG_SRC
+
+Corresponds to a .dsc file of a Debian source package.
+
+=item CTRL_PKG_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 $Dpkg::CONFDIR/origins/.
+
+=item CTRL_FILE_STATUS
+
+Corresponds to an entry in dpkg's F<status> file ($Dpkg::ADMINDIR/status).
+
+=item CTRL_CHANGELOG
+
+Corresponds to the output of dpkg-parsechangelog.
+
+=item CTRL_COPYRIGHT_HEADER
+
+Corresponds to the header control block in a F<debian/copyright> file in
+machine readable format.
+
+=item CTRL_COPYRIGHT_FILES
+
+Corresponds to a files control block in a F<debian/copyright> file in

+
+=item CTRL_COPYRIGHT_LICENSE

+are either new or overridden with a different behaviour.

+
+ return $self;
+}
+
+=item $c->set_options(%opts)
+
+Changes the value of one or more options. If the "type" option is changed,
+it is used first to define default values for others options. The option
+"allow_pgp" is set to 1 for CTRL_PKG_SRC, CTRL_FILE_CHANGES and
+CTRL_REPO_RELEASE and to 0 otherwise. The option "drop_empty" is set to 0
+for CTRL_INFO_PKG and CTRL_INFO_SRC and to 1 otherwise. The option "name"
+is set to a textual description of the type of control information.
+
+The output order is also set to match the ordered list returned by
+Dpkg::Control::Fields::field_ordered_list($type).

+=head1 NAME
+
+Dpkg::Control::FieldsCore - manage (list of official) control fields
+
+=head1 DESCRIPTION
+
+The modules contains a list of fieldnames with associated meta-data explaining
+in which type of control information they are allowed. The types are the
+CTRL_* constants exported by Dpkg::Control.
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item $f = field_capitalize($field_name)
+
+Returns the field name properly capitalized. All characters are lowercase,
+except the first of each word (words are separated by a hyphen in field names).
+
+=cut
+
+sub field_capitalize($) {
+ my $field = lc(shift);
+
+ # Use known fields first.
+ return $FIELDS{$field}{name} if exists $FIELDS{$field};
+
+ # Generic case
+ return join '-', map { ucfirst } split /-/, $field;
+}
+
+=item field_is_official($fname)
+
+Returns true if the field is official and known.
+
+=cut
+
+sub field_is_official($) {
+ my $field = lc shift;
+
+ return exists $FIELDS{$field};
+}
+
+=item field_is_allowed_in($fname, @types)
+
+Returns true (1) if the field $fname is allowed in all the types listed in
+the list. Note that you can use type sets instead of individual types (ex:
+CTRL_FILE_CHANGES | CTRL_CHANGELOG).
+
+field_allowed_in(A|B, C) returns true only if the field is allowed in C
+and either A or B.
+
+Undef is returned for non-official fields.
+
+=cut

+ return 0 unless $FIELDS{$field}{allowed} & $type;
+ }
+ return 1;
+}
+
+=item field_transfer_single($from, $to, $field)
+
+If appropriate, copy the value of the field named $field taken from the
+$from Dpkg::Control object to the $to Dpkg::Control object.
+
+Official fields are copied only if the field is allowed in both types of
+objects. Custom fields are treated in a specific manner. When the target
+is not among CTRL_PKG_SRC, CTRL_PKG_DEB or CTRL_FILE_CHANGES, then they
+are always copied as is (the X- prefix is kept). Otherwise they are not
+copied except if the target object matches the target destination encoded
+in the field name. The initial X denoting custom fields can be followed by
+one or more letters among "S" (Source: corresponds to CTRL_PKG_SRC), "B"
+(Binary: corresponds to CTRL_PKG_DEB) or "C" (Changes: corresponds to
+CTRL_FILE_CHANGES).
+
+Returns undef if nothing has been copied or the name of the new field
+added to $to otherwise.

+}
+
+=item field_transfer_all($from, $to)
+
+Transfer all appropriate fields from $from to $to. Calls
+field_transfer_single() on all fields available in $from.
+
+Returns the list of fields that have been added to $to.

+
+Return the type of the dependency expressed by the given field. Can

+=head1 NAME
+
+Dpkg::Control::HashCore - parse and manipulate a block of RFC822-like fields
+
+=head1 DESCRIPTION
+
+The Dpkg::Control::Hash object is a hash-like representation of a set of
+RFC822-like fields. The fields names are case insensitive and are always
+capitalized the same when output (see field_capitalize function in
+Dpkg::Control::Fields).
+The order in which fields have been set is remembered and is used
+to be able to dump back the same content. The output order can also be
+overridden if needed.
+
+You can store arbitrary values in the hash, they will always be properly
+escaped in the output to conform to the syntax of control files. This is
+relevant mainly for multilines values: while the first line is always output
+unchanged directly after the field name, supplementary lines are
+modified. Empty lines and lines containing only dots are prefixed with
+" ." (space + dot) while other lines are prefixed with a single space.
+
+During parsing, trailing spaces are stripped on all lines while leading
+spaces are stripped only on the first line of each field.
+
+=head1 METHODS
+
+=over 4
+
+=item $c = Dpkg::Control::Hash->new(%opts)
+
+Creates a new object with the indicated options. Supported options
+are:
+
+=over 8
+
+=item allow_pgp
+
+Configures the parser to accept OpenPGP signatures around the control
+information. Value can be 0 (default) or 1.
+
+=item allow_duplicate
+
+Configures the parser to allow duplicate fields in the control
+information. Value can be 0 (default) or 1.
+
+=item drop_empty
+
+Defines if empty fields are dropped during the output. Value can be 0
+(default) or 1.
+
+=item name
+
+The user friendly name of the information stored in the object. It might
+be used in some error messages or warnings. A default name might be set
+depending on the type.
+
+=item is_pgp_signed
+
+Set by the parser (starting in dpkg 1.17.0) if it finds an OpenPGP
+signature around the control information. Value can be 0 (default)
+or 1, and undef when the option is not supported by the code (in
+versions older than dpkg 1.17.0).

+=head1 NAME
+
+Dpkg::Control::Types - export CTRL_* constants
+
+=head1 DESCRIPTION
+
+You should not use this module directly. Instead you more likely
+want to use Dpkg::Control which also re-exports the same constants.
+
+This module has been introduced solely to avoid a dependency loop
+between Dpkg::Control and Dpkg::Control::Fields.
