+=head1 NAME
+
+Bugzilla::Webservice::Classification - The Classification API
+
+=head1 DESCRIPTION
+
+This part of the Bugzilla API allows you to deal with the available Classifications. 
+You will be able to get information about them as well as manipulate them.
+
+=head1 METHODS
+
+See L<Bugzilla::WebService> for a description of how parameters are passed,
+and what B<STABLE>, B<UNSTABLE>, and B<EXPERIMENTAL> mean.
+

+
+=item B<Description>
+
+Returns a hash containing information about a set of classifications.
+
+=item B<Params>
+
+In addition to the parameters below, this method also accepts the
+standard L<include_fields|Bugzilla::WebService/include_fields> and
+L<exclude_fields|Bugzilla::WebService/exclude_fields> arguments.
+
+You could get classifications info by supplying their names and/or ids. 
+So, this method accepts the following parameters:
+
+=over
+
+=item C<ids>
+
+An array of classification ids.
+
+=item C<names>
+
+An array of classification names.
+
+=back
+
+=item B<Returns>    
+
+A hash with the key C<classifications> and an array of hashes as the corresponding value.
+Each element of the array represents a classification that the user is authorized to see 
+and has the following keys:
+
+=over
+
+=item C<id>
+
+C<int> The id of the classification.
+
+=item C<name>
+
+C<string> The name of the classification.
+
+=item C<description>
+
+C<string> The description of the classificaion.
+
+=item C<sort_key>
+
+C<int> The value which determines the order the classification is sorted.
+
+=item C<products>
+
+An array of hashes. The array contains the products the user is authorized to
+access within the classification. Each hash has the following keys:
+
+=over
+
+=item C<name>
+
+C<string> The name of the product.
+
+=item C<id>
+
+C<int> The id of the product.
+
+=item C<description>
+
+C<string> The description of the product.
