For any pigz users out there,

pigz version 2.1.6 is now available at http://zlib.net/pigz/ . The
changes from 2.1.5 are:

- Added pigz.spec to distribution for RPM systems [Brown]
- Avoid some compiler warnings
- Process symbolic links if piping to stdout [Hoffstätte]
- Decompress if executable named "gunzip" [Hoffstätte]
- Allow ".tgz" suffix [Chernookiy]
- Fix adler32 comparison on .zz files

pigz is a parallel implementation of gzip that compresses using threads
in order to take the most advantage of multiple processors and cores.
pigz has all the functionality of gzip (and then some).
