In the Filter::Decompress example in the sources, the inflateInit could helpfully be made inflateInit (-WindowBits => MAX_WBITS() + WANT_GZIP_OR_ZLIB()) so as to accept both zlib format and gzip format. I tried the code with perl -MFilter::Decompress foo.pl.gz to run a compressed script and it silently did nothing -- until I hunted down to inflate() not liking the gzip header without a suitable WANT flag in the options. Since Compress::Zlib is supplied with perl 5.10, Filter::Decompress might even be installed ready to run, for cute use on .pl.gz files. Or was that how it was before and then taken away ... (Incidentally the "closure" version of Filter::Decompress may be missing a "my" for $err.)

I since realized Filter::Decompress is meant to go with the filtdef script, for a raw deflate stream. So instead of what I said before the files could just have comments cross-referencing each other so as to make clear what goes with what.

I didn't add -WindowBits => MAX_WBITS() + WANT_GZIP_OR_ZLIB() but I adjusted the usage docs a bit. See 1.46 -- Reini Urban
