/*
* 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
