+* .au mu-law audio data is treated as linear 8 bit unsigned value in the neighbourhood relation (with radius 1).
+  The neighbourhood relation should be defined with respect to the logarithmic nature of mu-law data.
+
+* steghide uses the classes hash_set and hash_map from sgi's implementation of
+  the standard template library. These two classes are not part of the official
+  C++ standard but part of the GNU's libstdc++. If you happen to be on a system
+  that does not include theses classes you won't be able to compile steghide.
+
+If you find a bug, please tell me (shetzl@chello.at) about it.

+Package: steghide
+Source: steghide (0.5.1-9.1)
+Version: 0.5.1-9.1+b1
+Architecture: amd64
+Maintainer: Ola Lundqvist <opal@debian.org>
+Installed-Size: 426
+Depends: libc6 (>= 2.2.5), libgcc1 (>= 1:4.1.1), libjpeg62-turbo (>= 1:1.3.1), libmcrypt4, libmhash2, libstdc++6 (>= 4.9), zlib1g (>= 1:1.1.4)

+Description: A steganography hiding tool
+ Steghide is steganography program which hides bits of a data file
+ in some of the least significant bits of another file in such a way
+ that the existence of the data file is not visible and cannot be proven.
+ .
+ Steghide is designed to be portable and configurable and features hiding
+ data in bmp, wav and au files, blowfish encryption, MD5 hashing of
+ passphrases to blowfish keys, and pseudo-random distribution of hidden bits
+ in the container data.
