+/* 
+ * stroke.c
+ * 
+ * This code uses Zint to encode data in QR Code and then output in
+ * the correct format to use StrokeScribe 2D font. This can be adapted
+ * to encode any matrix symbology using this font.
+ * 
+ * The same code can also be used to resolve PDF417 symbols with the
+ * StrokeScribe 417 font and linear symbols with the StrokeScribe 1D
+ * font, all of which are available from the same souce.
+ * 
+ * This code can be compiled with:
+ * 
+ * gcc -o stroke stroke.c -lzint
+ * 
+ * The fonts are available from:
+ * 
+ * https://strokescribe.com/en/free-version-barcode-truetype-fonts.html
