+=head1 NAME
+
+Bugzilla::WebService::Util - Utility functions used inside of the WebService
+code.
+
+=head1 DESCRIPTION
+
+This is somewhat like L<Bugzilla::Util>, but these functions are only used
+internally in the WebService code.
+
+=head1 SYNOPSIS
+
+ filter({ include_fields => ['id', 'name'], 
+          exclude_fields => ['name'] }, $hash);
+
+=head1 METHODS
+
+=over
+
+=item C<filter_fields>
+
+This helps implement the C<include_fields> and C<exclude_fields> arguments
+of WebService methods. Given a hash (the second argument to this subroutine),
+this will remove any keys that are I<not> in C<include_fields> and then remove
+any keys that I<are> in C<exclude_fields>.
