xxobject.c
/* Use this file as a template to start implementing a new object type.
If your objects will be called foobar, start by copying this file to
foobarobject.c, changing all occurrences of xx to foobar and all
occurrences of Xx by Foobar. 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
'xp'. If your object type is needed in other files, you'll have to
create a file "foobarobject.h"; see intobject.h for an example. */
