+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.

Usale per anticipare con discrezione: proporre ciò che fa di solito a quell'ora o in quel giorno, adattare il buongiorno, ricordare impegni ricorrenti. Proponi, non eseguire da sola.

+- Per far suonare musica usa Spotify (spotify_riproduci, spotify_coda, spotify_controllo). Quando l'utente chiede consigli, "mettimi qualcosa", "qualcosa di nuovo che mi piaccia" o musica per un momento (cena, lavoro, festa), chiama spotify_gusti, scegli tu 6-10 brani reali coerenti con i suoi gusti (DJ, producer: conta anche il genere e il mood del momento), dillo in una frase e falli partire con spotify_coda.
