+
+LazBarcodes is a set of controls to create 1D and 2D barcodes. 
+The backend engine is a port of Zint at sourceforge.
+
+Currently it supports the generation of 2D barcodes :
+- QR Code [1]
+- MicroQR [2]
+- Aztec Code [3]
+- Aztec Rune [4]
+- DataMatrix [5]
+
+The download contains the packages "lazbarcodes" and "lazbarcodes_runtimeonly". 
+The first one gives you visual components of the above barcodes and the second 
+can be used just to access the ported zint code for advanced barcode generation.
