-- This packages provides the implementation of a generic single-linked
-- list.
-- One instantiation is found in Gtk.Widget.Widget_Slist for a list of
-- widgets.
--
-- See the documentation of Glib.Glist for more information, it provides
-- the same API as this package.
-- Single linked lists are traversed the same way as double-linked lists,
-- even though most subprograms are less efficient than their
-- double-linked counterparts.
