/* 
 * daft.c
 * 
 * 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
 *
