 # Gregorian Chant Fonts
 
-Gregorio uses .ttf fonts to represent the various glyphs in Gregorian chant.  While there are hundreds of unique glyphs when you look at the entire body of Gregorian chant, these glyphs are usually composites of a relitively small number of components.  Rather than manage the huge number of glyphs, therefore, this project maintains the smaller component set for its fonts and then assembles these components into the various glyphs as part of the build process.  This minimizes the work load for the developers while still enabling customization at the glyph (rather than the component) level within documents created with Gregorio.
