+ * This code uses Zint to encode data into a USPS Intelligent
+ * Mail symbol, and then converts the output to "DAFT code"
+ * which is used by commercial fonts to display this and
+ * similar 4-state symbologies.
+ * 
+ * This code can be compiled with:
+ * 
+ * gcc -o daft daft.c -lzint
+ * 
+ * The output characters are:
+ * 
+ * D = Descender
+ * A = Ascender
+ * F = Full
+ * T = Tracker
