+=head1 NAME
+
+Symbian::DistributionPolicy - OO representation of a DISTRIBUTION.POLICY file.
+
+=head1 SYNOPSIS
+
+ # normally you would not create a policy object directly but
+ # use one returned by the Symbian::DistributionPolicy::Reader...
+
+ use Symbian::DistributionPolicy::Reader;
+
+ my $dpr = Symbian::DistributionPolicy::Reader->new();
+
+ my $policy = $dpr->ReadPolicyFile($path);
+
+ # then you may query the object using the methods below
+
+=head1 DESCRIPTION
+
+This module provides an object to represent the data in a DISTRIBUTION.POLICY
+file. The DISTRIBUTION.POLICY file specifies the policy information for all the
+source code files in the same directory. The directives are:
+
+=head2 Authorized LICENSEE_ID [until DATE]
+
+The C<Authorized> directive overrides any IPR restriction and makes available
+the source to the licensee with a specific I<LICENSEE_ID>. If the C<until>
+keyword is used then I<DATE> should be a string in the format dd/mm/yyyy. The
+exception made by this directive will expire at the end of this date. Only
+one C<Authorized> directive is allowed per I<LICENSEE_ID>.
+
+=head2 Category IPR_CATEGORY
+
+The C<Category> directive specifies the IPR category of the source.
+I<IPR_CATEGORY> may be any single character from the range A to Z. The default for
+unclassified source is X.
+
+=head2 Description TEXT
+
+The C<Description> directive specifies a one-line textual description of the
+directory content. I<TEXT> need not be quoted (in fact, it should not be).
+
+=head2 Expires DATE
+
+The C<Expires> directive specifies the date after which the directive(s) in the
+DISTRIBUTION.POLICY file become invalid. I<DATE> must be in dd/mm/yyyy format.
+
+=head2 Export STATUS
+
+The C<Export> keyword specifies whether the source is export restricted or not.
+The default is that it is not and this is equivalent to setting I<STATUS> to
+Unrestricted. Changing I<STATUS> to Restricted will enable this feature.
+
+=head2 OSD: ((COMMON|OPTIONAL) (SYMBIAN|REPLACEABLE)|REFERENCE/TEST) [NAME]
+
+The OSD line describes the nature of the source in five metrics: (COMMON vs.
+OPTIONAL and SYMBIAN vs. REPLACEABLE) or REFERENCE/TEST. The descriptions of
+these are available in Schedule 2 of the CKL.
+
+=head1 METHODS
+
+In addition to the constructor, getters and setters are provided for all policy
+directives:
+
+=begin text
+
+    +--------------+-------------------+----------------------+
+    | Directive    | Getter            | Setter               |
+    +--------------+-------------------+----------------------+
+    | Authorized   | Authorized        | SetAuthorizedUntil   |
+    | Category     | Category          | SetCategory          |
+    | Description  | Description       | SetDescription       |
+    | Expires      | Expires           | SetExpires           |
+    | Export       | ExportRestricted  | SetExportRestricted  |
+    | OSD          | See table below for individual methods.  |
+    +--------------+-------------------+----------------------+
+
+=end
+
+Individual OSD metrics getters and setters are detailed in the following table:
+
+=begin text
+
+    +-----------------+--------------+-----------------+
+    | Metric          | Getter       | Setter          |
+    +-----------------+--------------+-----------------+
+    | COMMON          | Common       | SetCommon       |
+    | OPTIONAL        | Optional     | SetOptional     |
+    | REPLACEABLE     | Replaceable  | SetReplaceable  |
+    | SYMBIAN         | Symbian      | SetSymbian      |
+    | REFERENCE/TEST  | Test         | SetTest         |
+    +-----------------+--------------+-----------------+
+
+=end
+
+=head2 new()
+
+Creates the policy object with default settings (cat=X, desc='', expires=never,
+export=unrestricted).
+
+=head2 Authorized($licensee_id[, $time])
+
+Returns the authorized status as a boolean (1=authorized, undef=not) for a
+given $licensee_id. If a $time is not specified the current time will be used.
+This is required if the C<Authorized> directive makes use of the I<until>
+keyword and the expiry time needs to be checked.
+
+=head2 SetAuthorizedUntil($licensee_id[, $date])
+
+Adds an authorized licensee to the policy. If an expiry date is specified it
+must be in dd/mm/yyyy format.
+
+=head2 Category()
+
+Returns the IPR category as a single-character string. If no IPR category exists
+in the distrubution file then 'undef' will be returned.
+
+=head2 SetCategory($cat)
+
+Sets the category. Will accept any single character from the range A to Z as a
+string in $cat.
+
+=head2 Common()
+
+Returns non-zero if the OSD metric COMMON is set.
+
+=head2 SetCommon($bool)
+
+Sets the OSD metric COMMON if $bool is true. Unsets it if $bool is false. Also
+sets the mutually exclusive OPTIONAL to the opposite.
+
+=head2 Description()
+
+Returns the description text (never undef - if blank you get an empty string).
+
+=head2 SetDescription($text)
+
+Sets the description text.
+
+=head2 Expires()
+
+Returns the expiry time specified in the file (or undef if not specified). It
+will be in UNIX (epoch) time format for your convenience. See Expired().
+
+=head2 SetExpires($date)
+
+Sets the expiry time to 23:59:59 on the date provided. $date should be a string
+in dd/mm/yyyy format.
+
+=head2 Expired([$time])
+
+Will test whether the policy data has (or will have) expired at the time
+specified. If no time is specified, the current time will be used - i.e. to
+determine whether the policy has already expired.
+
+=head2 ExportRestricted()
+
+Returns the export restricted status as a boolean (1=restricted,
+0=unrestricted, undef=information not available).
+
+=head2 SetExportRestricted($flag)
+
+Sets the export restricted status. $flag is a boolean (undef is allowed for
+false).
+
+=head2 Optional()
+
+Returns non-zero if the OSD metric OPTIONAL is set.
+
+=head2 SetOptional($bool)
+
+Sets the OSD metric OPTIONAL if $bool is true. Unsets it if $bool is false. Also
+sets the mutually exclusive COMMON to the opposite.
+
+=head2 Replaceable()
+
+Returns non-zero if the OSD metric REPLACEABLE is set.
+
+=head2 SetReplaceable($bool)
+
+Sets the OSD metric REPLACEABLE if $bool is true. Unsets it if $bool is false.
+Also sets the mutually exclusive SYMBIAN to the opposite.
+
+=head2 Symbian()
+
+Returns non-zero if the OSD metric SYMBIAN is set.
+
+=head2 SetSymbian($bool)
+
+Sets the OSD metric SYMBIAN if $bool is true. Unsets it if $bool is false. Also
+sets the mutually exclusive REPLACEABLE to the opposite.
+
+=head2 Test()
+
+Returns non-zero if the OSD metric REFERENCE/TEST is set.
+
+=head2 SetTest($bool)
+
+Sets the OSD metric REFERENCE/TEST if $bool is true. Unsets it if $bool is
+false.
