SUMMARY = "A parallel implementation of gzip"
DESCRIPTION = "pigz, which stands for parallel implementation of gzip, is a \
fully functional replacement for gzip that exploits multiple processors and \
multiple cores to the hilt when compressing data. pigz was written by Mark \
Adler, and uses the zlib and pthread libraries."
