     0.21 Plug-in updates

Requisite Plug-in Functions
   See CAD::Drawing::IO for a description of the plug-in architecture.

 check_type

     $type_over_ride = check_type($filename, $type);

Back-End Methods
   These are called directly from CAD::Drawing::IO

 save

   This needs some work still.

     $drw->save($filename, \%options);

Internal Methods
   The back-end methods should definitely not be called directly, and these
   should not even be called from the backend code.

 dwgtype

   Returns the toolkit constants corresponding to some human-readable
   version and type names.

     ($type, $version) = dwgtype($type);
