Very nice!

Can it be fed straight gzip file data, or does it need the file header
stripping from it first?  I think I usually pass everything to zlib's
inflate, but it may well detect and skip it.


Hi,

The whole gz file. In fact I explicitly test for the gzip "magic  
number" bytes at the beginning - it's one of the few opportunities to  
sanity-check the input! Otherwise, a typo in your source address would  
be very likely to crash the machine, and I thought this was perhaps a  
little user-unfriendly...


Cheers,
Andrew

PS. By the way, Sourceforge have approved the project and so the  
source files are now available.
