Calgary Challenge Update

I didn’t see it mentioned here but Alexander Ratushnyak won some prize money on the Calgary challenge, http://mailcom.com/challenge/ with an entry of 596,314 bytes on Oct. 25. It consists of a solid archive of 588,183 bytes, plus the decompressor (as C++ source) packed into a RAR
archive. The source is uncommented to save space but appears to be a variant of a previous entry by Przemyslaw Skibinski, which is itself a variant of PAsQDa with a tiny, built in dictionary. The latest version is an improvement of 7KB, consisting of a 4KB improvement in the
archive size and 3KB in the compressed size of the decompressor.
