Thanks for the pointer. The above thread is about decompressing a file
in the ZLIB compressed data format (RFC 1950). Both ZLIB and GZIP (RFC
1952) are wrappers around DEFLATE-compressed data. I'm interested in
the latter.

For the archives, this thread shows how to obtain a DEFLATE-compressed
data stream from a GZIP file:

This worked perfectly.

Thanks,

Tom
