+=head1 NAME
+
+Bugzilla::WebService::Server - Base server class for the WebService API
+
+=head1 DESCRIPTION
+
+Bugzilla::WebService::Server is the base class for the individual WebService API
+servers such as XMLRPC, JSONRPC, and REST. You never actually create a
+Bugzilla::WebService::Server directly, you only make subclasses of it.
+
+=head1 FUNCTIONS
+
+=over
+
+=item C<bz_etag>
+
+This function is used to store an ETag value that will be used when returning
+the data by the different API server modules such as XMLRPC, or REST. The individual
+webservice methods can also set the value earlier in the process if needed such as
+before a unique update token is added. If a value is not set earlier, an etag will
+automatically be created using the returned data except in some cases when an error
+has occurred.
