+%description
+libdvbcsa is a free implementation of the DVB Common
+Scrambling Algorithm - DVB/CSA - with encryption and
+decryption capabilities.
+Features
+ * Portability. This library has been successfully
+ tested on different processors with 32 bits,
+ 64 bits and 128 bits word width, little-endian
+ and big-endian bytes ordering.
+ * Performance. It comes in two flavors: a classical
+ single packet implementation and a faster parallel
+ bitslice implementation.
+ * The parallel implementation can take advantages
+ of MMX, SSE or Altivec instruction sets. Parallel
+ implementation can process Mpeg TS packets at
+ 300Mbps or more on recent processors.
+ * Freedom. libdvbcsa is released under the General
+ Public License, ensuring it will stay free, and used
+ only for free software products.
+ * Simplicity. The API comes with only 5 functions
+ fot the single packet implementation, and 6 functions
+ for the parallel bitslice implementation.
