-- This package implements the notion of tab stops, to be used in the
-- context of a pango.layout or its higher level interface Gtk.Text_View.
--
-- This package allows you to define precise location (in pixels) in the
-- layout on which the <tab> character in the text will be aligned. This
-- allows you to easily align columns of text even when using a proportional
-- font for instance. This is similar to the standard interface that most
-- word processing tools provide through tab stops in their ruler bars.
