+'''Write mapping of graphite names to new graphite names based on:
+   - an original ttf font
+   - the gdl file produced by makeGdl when original font was produced
+   - a csv mapping glyph names used in original ttf to those in the new font
+   - pysilfont's gdl library - so assumes pysilfonts makeGdl will be used with new font'''
