+Package: libquirc1

+Description: QR code recognition library
+ Quirc is a library for extracting and decoding QR codes from images.
+ It has several features which make it a good choice for this purpose:
+ .
+  * It is fast enough to be used with realtime video
+  * It has a robust and tolerant recognition algorithm
+  * It is easy to use, with a simple API
+  * It is small and easily embeddable
+  * It has a very small memory footprint
+  * It uses no global mutable state, and is safe to use in a multithreaded
+    application
+  * ISC-licensed, with almost no restrictions regarding use and/or modification
