elements, or the empty list.

The first element is the name which shows up in the menu.  The second
is the `tempo' identifier (The string \"erlang-\" will be added in
front of it).  The third is the skeleton descriptor, a variable
containing `tempo' attributes as described in the function
`tempo-define-template'.  The optional fourth elements denotes a
function which should be called when the menu is selected.

Functions corresponding to every template will be created.  The name
of the function will be `tempo-template-erlang-X' where `X' is the
tempo identifier as specified in the second argument of the elements
in this list.

A list with zero elements means that the a horizontal line should
be placed in the menu.")
