+    \brief   AS-DCP file manipulation utility
+
+  This program provides command line access to the major features of the asdcplib
+  library, and serves as a library unit test which provides the functionality of
+  the supported use cases.
+
+  For more information about asdcplib, please refer to the header file AS_DCP.h
+
+  WARNING: While the asdcplib library attempts to provide a complete and secure
+  implementation of the cryptographic features of the AS-DCP file formats, this
+  unit test program is NOT secure and is therefore NOT SUITABLE FOR USE in a
+  production environment without some modification.
+
+  In particular, this program uses weak IV generation and externally generated
+  plaintext keys. These shortcomings exist because cryptographic-quality
+  random number generation and key management are outside the scope of the
+  asdcplib library. Developers using asdcplib for commercial implementations
+  claiming SMPTE conformance are expected to provide proper implementations of
+  these features.
