+=item check_options
+
+Pass an I<$options> hashref that contains the values to be
+inserted or updated for any FS::part_pkg::MODULE.pm.
+
+For each key in I<$options>, validates the value by calling
+the 'validate' subroutine defined for that option e.g.
+FS::part_pkg::MODULE::plan_info()->{$KEY}->{validate}. The
+option validation function is only called when the hashkey for
+that option exists in I<$options>.
+
+Then the module validation function is called, from
+FS::part_pkg::MODULE::plan_info()->{validate}
+
+Returns error message, or empty string if valid.
+
+Invoked by L</insert> and L</replace> via the equivalent
+methods in L<FS::option_Common>.
