+; This function allows the user to change the specific fonts, leaving others
+; to the default values. This way, "make-pango-font-tree"'s syntax doesn't
+; have to change from the user's perspective.
+;
+; Usage:
+; \paper {
+; #(define fonts
+; (set-global-fonts
+; #:music "gonville" ; (the main notation font)
+; #:roman "FreeSerif" ; (the main/serif text font)
+; ))
+; }
+;
+; Leaving out "#:brace", "#:sans", and "#:typewriter" leave them at
+; "emmentaler", "sans-serif", and "monospace", respectively. All fonts are
+; still accesible through the usual scheme symbols: 'feta, 'roman, 'sans, and
+; 'typewriter.
