Wouldn't it be nice to be able to put labels on the glyphs? Let's extend the syntax of a Glyph line. We need a keyword "labeled" and a text string for the label. Labels can be positioned to the left of, to the right of, above, or below the glyph. So another keyword specifying the position is needed.
