/* Use this file as a template to start implementing a module that
also declares object types. All occurrences of 'Xxo' should be changed
to something reasonable for your objects. After that, all other
occurrences of 'xx' should be changed to something reasonable for your
module. If your module is named foo your sourcefile should be named
foomodule.c.
2002-05-23 12:49:38 -03:00
You will probably want to delete all references to 'x_attr' and add
your own types of attributes instead. Maybe you want to name your
local variables other than 'self'. If your object type is needed in
other files, you'll have to create a file "foobarobject.h"; see
intobject.h for an example. */
