+// Attach this header file to your sketch to use the GFX Free Fonts. You can write
+// sketches without it, but it makes referencing them easier.
+
+// This calls up ALL the fonts but they only get loaded if you actually
+// use them in your sketch.
+//
+// No changes are needed to this header file unless new fonts are added to the
+// library "Fonts/GFXFF" folder.
+//
+// To save a lot of typing long names, each font can easily be referenced in the
+// sketch in three ways, either with:
+//
+//    1. Font file name with the & in front such as &FreeSansBoldOblique24pt7b
+//       an example being:
+//
+//       tft.setFreeFont(&FreeSansBoldOblique24pt7b);
+//
+//    2. FF# where # is a number determined by looking at the list below
+//       an example being:
+//
+//       tft.setFreeFont(FF32);
+//
+//    3. An abbreviation of the file name. Look at the list below to see
+//       the abbreviations used, for example:
+//
+//       tft.setFreeFont(FSSBO24)
+//
+//       Where the letters mean:
+//       F = Free font
+//       M = Mono
+//      SS = Sans Serif (double S to distinguish is form serif fonts)
+//       S = Serif
+//       B = Bold
+//       O = Oblique (letter O not zero)
+//       I = Italic
+//       # =  point size, either 9, 12, 18 or 24
+//
+//  Setting the font to NULL will select the GLCD font:
+//
+//      tft.setFreeFont(NULL); // Set font to GLCD
