Zlib decompression - Any ideas?

[Brian Yennie]

Ken,

Can you compress a copy of the original file with Rev, and compare it  
to the zlib compressed copy? Does the data look totally different, or  
maybe just off by a few bytes / headers?

If you have a MacOS X machine (or Linux) handy, you can use gzip and  
gunzip as command-line equivalents of compress() and decompress() and  
see how those results compare as well...
